Cheap Powerful Wave of Conviction Miner 3.28
The core idea behind this build is elegantly simple and brutally effective: use mines to cast Wave of Conviction so each mine detonation becomes an instant nova that frontloads damage. That frontloading removes the need to stack temporary buffs or long ramp windows and instead lets you create predictable, repeatable bursts of single‑target damage. In patch 3.28 the interaction between mine deployment, Minefield style supports, and nova behavior makes the Wave of Conviction miner a top meta pick for players who want a strong league start and a clear path to endgame bossing. The miner delivery system multiplies effective casts and gives you precise control over timing, which is the difference between a build that occasionally spikes and one that reliably deletes bosses.
Core mechanics and how mines change the nova game
Wave of Conviction produces a circular nova that expands and then contracts. When you use mines as the delivery method, each mine detonation spawns a nova centered on the mine. Because you can place and detonate multiple mines in quick succession, you can create several novas in a short window without relying solely on cast speed. The key mechanical advantage is timing: if you stagger detonations so each nova completes its expansion and contraction, bosses often get hit twice by the same nova cycle, effectively doubling the damage per mine. Supports that increase the number of mines detonated per cast or the speed at which you can deploy and detonate mines multiply this effect. The miner approach also lets you control nova origin precisely, which is invaluable against moving bosses and in tight arena spaces.
Ascendancy choices and why they matter
Two ascendancies stand out for this playstyle because they complement the miner’s need for both throughput and survivability. Trickster offers mobility, recovery, and defensive options that make it easier to reposition and survive while you set mines. Trickster’s recovery mechanics pair well with the miner’s rhythm because you often need to reposition between volleys and recover quickly. Saboteur, on the other hand, gives direct mine bonuses and utility that increase mine damage and control. Saboteur can push raw mine throughput higher, but it often requires a bit more investment in life and defenses. Both ascendancies can reach S‑tier performance; choose Trickster for a smoother league start and easier survivability, or Saboteur for maximum mine-focused damage and utility.
Gem setup and socket priorities
Your main skill is Wave of Conviction linked to mine supports. The build wants a 6‑link for bossing, though a 4‑link is serviceable early. The core supports to prioritize are Minefield, Controlled Destruction, Elemental Focus or crit supports depending on your route, and a mine speed or mine throw support. Minefield multiplies the number of mines detonated and is the single most important support for raw damage. Controlled Destruction is ideal for non‑crit because it increases spell damage at the cost of crit chance, while crit routes swap it for Increased Critical Strikes and Increased Critical Damage. For mapping you will swap in Increased Area of Effect or Concentrated Effect depending on whether you want clear speed or single‑target punch. Keep a movement skill such as Dash or Flame Dash, a defensive skill like Steelskin or Immortal Call if you can support it, and a curse such as Assassin’s Mark or Despair depending on whether you lean physical or chaos conversion. A totem or decoy can be useful for tanking while you set mines, but it is optional.
Passive tree direction and jewel priorities
The passive tree should prioritize life, mine damage, spell damage, cast speed for mines, and critical strike nodes if you choose crit. Early on, take life nodes and any nearby mine or trap nodes you can reach without sacrificing survivability. Midgame, pick up cluster jewels that boost mine damage or spell damage and socket large jewels that increase single‑target damage. Endgame, optimize for maximum mine and spell scaling, focusing on critical chance and multiplier if you went crit. If you prefer a non‑crit route, stack spell and mine damage plus flat elemental damage and penetration where possible. Jewels are crucial: look for increased mine damage, increased spell damage, and flat elemental damage on jewels. Large cluster jewels that add mine or spell damage are extremely valuable and should be slotted as soon as you can afford them.
Gear priorities and crafting roadmap
Gear priorities are straightforward: life, mine damage, cast/mine speed, and single‑target scaling. Early league start, buy cheap rares with high life and resistances. A crafted life chest is the single best early investment. Gloves and boots should prioritize life and movement speed; gloves with mine damage or cast speed are ideal. A helmet with +1 to socketed gems or increased mine speed is a midgame upgrade that dramatically improves performance. Rings and amulets should focus on life and damage; a ring that shifts nova origin toward the target or otherwise manipulates nova behavior is a powerful mid‑ to late‑game purchase if you can afford it. Endgame targets are crit chance and multiplier if you went crit, or high spell/mine damage and penetration for non‑crit. Crafting priorities are life on chest, mine damage on gloves and boots, and resistances everywhere. Use essences and fossils to target mine and spell mods when crafting. If you have currency, buy a helmet with +1 to socketed gems or a ring that manipulates nova origin; these are the most impactful purchases after a life chest.
Playstyle rhythm and bossing tactics
The miner is a rhythm class. Pre‑place mines in a pattern that allows you to detonate them in staggered bursts so novas do not overlap wastefully. Against single targets, place a ring of mines around the boss and detonate them in waves so each nova’s expansion and contraction hits the boss twice. This double‑hit is the key to the build’s single‑target power. Use movement to dodge boss telegraphs between volleys and keep a quick detonate or a mine detonate on a keybind for emergency burst. For mapping, widen your mine placement to cover more ground and swap in Increased Area of Effect to clear packs. For bosses, tighten your mine placement and use Concentrated Effect if you need more single‑target damage. Always be mindful of the one‑wave‑at‑a‑time rule: detonating too many mines at once in the same spot can waste potential hits. Staggering and spacing are the solution.
Leveling strategy and early progression
Leveling is forgiving. Start with a simple mine skill or a generic spell until you can afford the core supports for Wave of Conviction. Early levels should focus on life and resistances; you don’t need perfect gear to get going. As soon as you can link Minefield with Wave of Conviction and a damage support, transition into the miner playstyle. Prioritize a life chest and a movement skill to speed up mapping. By the time you reach mid‑maps, you should have your main 6‑link and a helmet with useful mods. The build is an excellent league starter because it scales well with a few key purchases and doesn’t require expensive uniques to function.
Budget variants and upgrade path
A cheap league‑start version uses rares with life and resistances, a 4‑link with Minefield and a damage support, and a crafted life chest. This version will carry you through early maps and allow you to farm currency. A mid‑budget upgrade is a helmet with +1 to socketed gems or a ring that manipulates nova origin; these items provide a huge power spike for a moderate investment. The aspirational endgame variant stacks crit chance and multiplier or high spell/mine damage jewels and crafted gear. The build scales linearly with investment: small upgrades yield large single‑target gains, which makes it friendly to players who want to start cheap and upgrade over time.
Mapping approach and clear speed tuning
Mapping and clear speed are solid but not the build’s primary selling point. For mapping, widen mine placement and use Increased Area of Effect or Minefield to cover more ground. Use movement speed boots and a movement skill to keep pace through maps. If you want faster clear, sacrifice a little single‑target power for area supports and swap to a more AoE‑focused link. The miner is versatile: it can be tuned for fast mapping or tuned for maximum single‑target damage depending on your gem choices and gear. When mapping, keep an eye on pack density and adjust mine spacing so you don’t waste mines on low‑value targets.
Defensive options and flask usage
Survivability is straightforward: stack life, use defensive ascendancy nodes, and keep a movement skill to dodge mechanics. Trickster’s recovery and movement bonuses make it easier to survive without heavy investment in defensive uniques. If you prefer Saboteur, you’ll need to invest a bit more in life and resistances early on. Use flasks aggressively: a life flask with instant recovery and a utility flask for bleed removal or curse removal are essential. If you find yourself dying to one‑shot mechanics, increase your life pool and consider adding an endurance charge or a totem to absorb hits while you set mines.
Advanced optimizations and cluster jewel choices
Advanced players should prioritize cluster jewels that add mine or spell damage and socket small jewels that increase cast speed or critical chance. Large cluster jewels that add mine or spell damage are extremely valuable. Small cluster jewels that increase cast speed or critical chance can be slotted to fine‑tune your build. Endgame players should aim for a combination of high‑tier jewels, a crafted chest with life and mine damage, and a helmet with +1 to socketed gems. If you go crit, invest in critical chance and multiplier on rings and amulet, and use jewels that boost crit. If you go non‑crit, invest in flat elemental damage and penetration.
Common mistakes and how to fix them
The most frequent error is detonating mines all at once in the same spot, which wastes potential hits because novas overlap and cancel each other’s effectiveness. The fix is to stagger detonations and space mines so each nova has room to expand and contract. Another mistake is neglecting life and resistances early; the miner’s damage is strong, but survivability is still essential. Finally, don’t ignore movement: the ability to reposition between volleys is what separates a good miner from a great one. Practice your cadence in safe encounters before attempting the hardest bosses.
Practical 20 hour progression plan
In your first 20 hours, focus on a few clear goals. Buy a life chest and a movement skill, secure a 4‑link with Minefield and a damage support, and then upgrade to a 6‑link as soon as possible. Pick up a helmet with +1 to socketed gems or craft one when you have the currency. Invest in jewels that increase mine and spell damage. Once you have a solid mid‑game setup, focus on mapping to farm currency and buy a ring or amulet that manipulates nova origin if available. From there, buy high‑tier jewels and craft your chest for endgame performance.
Why this build is friendly to new and returning players
This build is approachable because it scales well from cheap rares into expensive endgame gear. You can start with minimal investment and still clear maps and bosses reliably. The miner’s predictable damage and straightforward playstyle make it a great choice for players who want to focus on learning boss mechanics rather than juggling complex rotations. The rhythm‑based gameplay is satisfying and forgiving once you master mine spacing and detonation timing.
Endgame loop and farming strategy
The endgame loop is simple: farm maps to buy upgrades, craft jewels and gear to increase mine and spell damage, and practice your mine cadence for the hardest bosses. The build’s linear scaling means that each upgrade yields noticeable improvements in single‑target damage. Once you have a solid helmet, a crafted chest, and a few high‑tier jewels, you’ll be able to tackle the toughest content with confidence. Use mapping strategies that maximize currency returns while targeting the mods you need for crafting.
Final tips for mastering the cadence
Mastering the cadence is the final step to making this build feel effortless. Practice placing mines in patterns that let you detonate in two or three staggered bursts. Learn the timing of the nova expansion and contraction so you can reliably get double hits on bosses. Use movement to reposition between volleys and keep a quick detonate for emergency burst. With practice, the miner becomes a machine: predictable, repeatable, and devastating.

Passive Tree Snapshot
Start at the Witch or Shadow depending on your ascendancy choice. Your early pathing should prioritize life nodes and the nearest mine and spell clusters. Aim to secure a solid life backbone first, then route toward the mine‑specific nodes that increase mine damage, mine throwing speed, and mine area. After that, take spell and elemental damage nodes and any nearby critical clusters if you chose a crit route. The snapshot below describes the major node groups and the recommended order to pick them so you can copy the path into Path of Building or follow it while respeccing.
Begin by taking the immediate life cluster near the Witch/Shadow start and the small life nodes along the way. Move toward the Spell Damage and Cast Speed clusters that sit between the start and the central mine nodes. From there, path to the Mine Damage and Mine Throwing Speed nodes; these are the core offensive pillars. After securing those, take the large Life Wheel in the center of the tree to reach the major spell and elemental damage clusters that amplify Wave of Conviction.
Keystone selection depends on your defensive philosophy. Avoid keystones that punish your survivability; instead, take Mind Over Matter only if you have a reliable way to convert damage to mana and a very high mana pool. Most players will skip keystones and rely on ascendancy and flasks for defense, keeping the passive tree focused on life and damage.
Ascendancy Path
If you choose Trickster, prioritize nodes that grant recovery, movement, and increased damage while maintaining survivability. Your ascendancy order should be the node that grants life and recovery on kill, then the node that increases damage and evasion, and finally the node that improves mine or spell throughput. Trickster’s recovery and movement make it the easiest league start option and smooths the learning curve for mine cadence.
If you choose Saboteur, take the ascendancy nodes that directly buff mines first: increased mine damage, additional mines, and utility that improves mine placement and detonation. Saboteur pushes raw mine throughput higher and pairs well with cluster jewels that add mine damage or extra mine detonations.
Either ascendancy should end with the node that provides the most consistent damage or survivability for your playstyle. Trickster for safer play and Saboteur for maximum mine control.
Cluster Jewels and Jewel Priorities
Large cluster jewels are high value. Look for mods that add increased mine damage, increased spell damage, increased cast speed, or increased area of effect depending on whether you favor single target or mapping. A typical large jewel socketed into the tree should provide a mix of mine and spell scaling plus a small life roll. Small cluster jewels should be used to pick up extra cast speed, critical chance, or flat elemental damage. Regular jewels should prioritize flat elemental damage to spells, increased spell damage, and increased mine damage. Aim for at least two large cluster jewels by midgame; they are the single biggest passive investment for scaling this build.
Recommended jewel mods in order of priority are increased mine damage, increased spell damage, flat elemental spell damage, cast speed, and then life. If you go crit, prioritize critical chance and multiplier on jewels that don’t sacrifice too much life.
Key Passive Nodes to Target
Take the nearest life wheels and the large life keystones early. Secure the Mine Damage cluster and the Mine Throwing Speed nodes as soon as possible. After that, pick up Spell Damage and Elemental Damage clusters that sit along the route to your ascendancy. If you went crit, detour to the critical chance and multiplier clusters and then return to life and mine nodes. If you went non‑crit, continue to stack spell and mine damage plus flat elemental damage and penetration.
Aim for a final passive layout that includes: 4,000+ effective life (endgame target), multiple mine damage clusters, at least one large cluster jewel with mine/spell mods, and either a crit cluster or additional spell damage depending on your route.
Bandwidth and Pathing Tips
Minimize wasted travel by taking the shortest route that hits life and mine nodes. Use respec points early to correct inefficient paths; the build is flexible so small pathing changes are acceptable. If you plan to use a +1 helmet or a ring that manipulates nova origin, prioritize the nodes that increase mine damage and cast speed earlier because those items amplify the same passive benefits.
If you plan to use cluster jewels, leave open sockets in the mid and late tree where large cluster jewels naturally fit; this reduces respec cost later. When placing large jewels, ensure they connect to both mine and spell clusters to maximize synergy.
Example Node Order for First 100 Passive Points
Secure immediate life nodes and the small life wheel near your start. Move to the nearest mine damage cluster and pick up mine throwing speed. Route to the central life wheel to expand your pool, then take the spell damage cluster that leads toward your ascendancy. After ascendancy, pick up the next mine damage cluster and socket a small jewel for cast speed or flat damage. By 100 points you should have life, mine damage, and a path toward your chosen ascendancy.
Endgame Targets on the Tree
Endgame, your passive tree should show heavy investment in mine damage, spell damage, and life. You should have at least one or two large cluster jewels socketed, critical clusters if you went crit, and all nearby mine nodes taken. Your final tree should be balanced: enough life to survive boss mechanics, enough mine throughput to maintain cadence, and enough single‑target scaling to delete bosses quickly.
Quick Respec Priorities
If you need to respec for survivability, drop a few offensive nodes and pick up nearby life wheels or defensive clusters. If you need more damage, add cluster jewels or take the remaining mine damage clusters. Respecing is cheap early and more expensive later; plan your path to minimize future respec cost by leaving flexible routes open.
