This version of the Abyssal Lich Cast on Critical build is designed as a true endgame setup, intended for characters who have already reached high‑tier mapping and unlocked the Abyssal Lich ascendancy after defeating Kulemak, something only possible once you’re comfortably farming T14+ maps. Before that point, you follow the same passive tree pathing but play on the regular Lich ascendancy, transitioning into the full power spike once Abyssal Lich becomes available.

At its core, the build revolves around the synergy between Entangle and Thunderstorm. Entangle carpets the battlefield with long‑lasting fissures that slow enemies and apply constant physical pressure through rapidly attaching vines. Thunderstorm acts as the catalyst, repeatedly striking enemies with lightning hits that push Entangle into the Overgrown state, dramatically increasing its uptime and density. This creates a persistent damage field that weakens everything around you before the real finisher comes into play.

The defining mechanic of the build is Cast on Critical Detonate Dead. Every time you crit, Detonate Dead automatically triggers, consuming nearby corpses and unleashing powerful explosions. This creates a natural chain reaction: Entangle weakens and slows, Thunderstorm empowers it, Detonate Dead fires, enemies die, ascendancy explosions spread, and the cycle repeats. The result is a smooth, reactive clearing pattern that feels both controlled and explosive without requiring manual corpse targeting.

For players seeking a high ceiling, this setup offers some of the strongest crit‑scaling potential in the game. Endgame chase items - high‑tier crit amulets, Heart of the Well variants, or belts like Headhunter and Mageblood - can massively accelerate your tempo, enabling near‑constant crit chains and turning Detonate Dead into a screen‑wide cascade of explosions. None of these items are required for the build to function, but each one pushes your performance into a new tier, transforming your crit‑triggered detonations into devastating bursts capable of deleting bosses in seconds.

1. Gameplay

This build plays as a fast, reactive crit‑chain detonator, where your damage comes from constant Cast on Critical Detonate Dead triggers rather than manual casting. You carpet the ground with Entangle fissures while Thunderstorm waters them, pushing those fissures into the Overgrown state and supplying a steady stream of crits. Every crit automatically fires Detonate Dead, turning corpses into explosions that chain across packs and wipe the screen. As enemies die, the Abyssal Lich ascendancy adds even more on‑death explosions, creating a natural cascade of blasts without extra inputs. For tougher rares and bosses, you weave in Thrashing Vines and Bonestorm for focused single‑target pressure. For optimal performance, play with Thunderstorm on weapon set 2, and all other skills on weapon set 1.

2. Build's PROS & CONS

PROS

Almost UNKILLABLE
Explosive clear
Massive scaling potential
Very fast build

CONS

Easy to break if mis‑configured
Can struggle with mana sustain

3. Leveling tips

This build can be leveled as a plant build from level 1, making early progression smooth and consistent. In Act 1 you support your setup with Volcano for extra coverage and early damage, and from Act 2 onward you simply continue using the same core gems you’ll run in the final version - Entangle, Thunderstorm and your plant supports.
The only major difference is that Cast on Critical comes much later. You should not use Cast on Critical Detonate Dead during the campaign and low tier maps; the crit chance is far too low and the setup won’t function properly. Instead, play the natural plant‑based version until you reach endgame maps and acquire enough critical strike chance to reliably trigger Detonate Dead. Once your crit engine is online, you can safely transition into the full Abyssal Lich CoC version.

5. Final Gems links

[DPS] Cast on Critical Detonate Dead setup
	Cast on Critical - lets you automatically trigger linked spells whenever you land a Critical Strike. In this Abyssal Lich setup, it adds smooth, passive DPS during mapping and helps amplify your damage when multiple plants are detonating at once. We support it with Rapid Casting II to speed up the triggered spell, Efficiency II and Energy Retention to reduce its cost.
	Atziri's Communion - forces supported skills to reserve a portion of your Life equal to 66% of their base Spirit Reservation, allowing you to deliberately reserve your Life pool and maintain a permanent Low Life state. This is essential for unlocking powerful low‑life bonuses.
	Detonate Dead - consumes nearby corpses to create strong AoE explosions, giving the build an additional burst tool that complements Rupture the Flesh detonations. We support it with Magnified Area II to widen the blast radius.
	Energy Retention
	Efficiency
	Execute III

[DPS] Entangle setup
	Entangle - creates a crawling fissure that damages and Slows enemies while attaching Vines to anything caught near it. We support it with Accelerated Growth II to speed up how quickly your fissures reach their empowered Overgrown state, Execute III to boost Entangle’s damage, Branching Fissures II to widen the area covered by your fissures and help them attach Vines to more targets, and Zenith II to grant a strong “more damage” multiplier while you stay above 90% Mana; and Trickster’s Shard, which creates Fractured Mimics that store and later release additional casts of your supported spells, giving you periodic synchronized bursts without altering your rotation.

It delivers heavy, focused hits that supplement Entangle’s sustained pressure whenever you need extra burst on priority targets. We support it with Blindside to increase the damage dealt to blinded enemies, Execute III to massively boost damage, Zenith II for a strong “more damage” multiplier while staying above 90% Mana, Heft to enhance the impact of each vine slam, and Rapid Casting II to smooth out the skill and reduce downtime between vine drops.

6. Gear Setup

Your gear setup focuses on stacking Energy Shield as your primary defense, while still valuing Life because this build does not use Chaos Inoculation. This hybrid approach gives you a massive effective HP pool and makes gearing far more flexible than strict CI setups. Your items should cover Elemental Resistances, attributes and rarity.

Offensively, your biggest upgrades come from Weapon and Jewellery - these slots provide the largest boosts to crit chance, crit multi, gem levels, and spell damage. The rest of your gear should fill in Extra Cold/Lightning and any missing Cast Speed to keep your Entangle and Thunderstorm loop smooth.

Stat priorities on items:

Cap Elemental Resistance
Critital Hit Chance/Critical Bonus Damage
ES
Spell Damage
Cast Speed
Item Rarity
Life

(Weapon) Rare Staff - every one of its core modifiers directly scales both sides of your damage: your Plant skills and your Detonate Dead explosions. High gem levels massively boost your base damage, while the Spell Crit Chance, Extra Cold/Lightning, and Spell Damage multipliers supercharge your crit engine.
Min. requirements: +4 to Level of all Physical Spell Skills 95% increased Critical Hit Chance for Spells Gain 15% of damage as Extra Lightning/Cold Damage 120% increased Spell Damage Optional affixes: Gain #% of damage as Extra Fi Damage #% increased Spell Physical Damage #% increased Cast Speed
(Weapon) Rare Staff - used purely to upgrade Thunderstorm - your utility skill that keeps Plants in the Overgrown state. The +levels, Cast Speed and Extra Lightning Damage significantly improve Thunderstorm’s hit frequency and consistency, which directly boosts your CoC uptime and overall smoothness of gameplay. It’s not a damage weapon by itself, but it enhances the skill that makes your whole build function.
Min. requirements: +4 to Level of all Lightning Spell Skills 35% increased Cast Speed Gain 15% of damage as Extra Lightning Damage Optional affixes: #% increased chance to Shock #% increased Spell Damage
(Helmet) Atziri's Disdain - Atziri’s Disdain greatly boosts your Energy Shield by converting a portion of your Life into extra ES, which fits perfectly with your hybrid setup. Thanks to Eternal Life, the “10% of damage taken bypasses Energy Shield” line effectively works as 10% less damage taken, since that portion hits Life but your Life cannot be reduced while ES is active. This makes the helmet a deceptively strong defensive option for the build.
+(60—100) to maximum Mana (10—20)% increased Rarity of Items found Gain (10—15)% of maximum Life as Extra maximum Energy Shield 10% of Damage taken bypasses Energy Shield
(Amulet) Rare Amulet - look primarily for ES, Crit and the Level of all Spell Skills, but it is also a potent source of Resistances and Rarity. Instil the Zarokh's Gift
Min. requirements: 25% increased Critical Damage Bonus +2 to Level of all Spell Skills 30% increased maximum Energy Shield Optional affixes: #% increased Spell Damage #% total Elemental Resistance +# to maximum Life
(Ring) Rare Ring - generic resistance ring that mainly serves as a defensive slot. Its high total Elemental Resistances make it extremely useful for capping res early and mid‑game, while Spell Damage and optional Life/Cast Speed help smooth out your damage and sustain.
Min. requirements: +30% increased Spell Damage +40% total Elemental Resistance Optional affixes: #% increased Rarity of Items found +# to maximum Life #% increased Cast Speed
(Ring) Rare Ring - crit‑focused ring that you ideally craft using the Breach Tree, since it offers the best access to strong Critical Chance and Critical Spell Damage mods. This version is a pure offensive upgrade, boosting your crit engine and improving Cast on Critical consistency.
Min. requirements: +30% increased Spell Damage 30% increased Critical hit Chance for Spells 30% increased Critical Spell Damage bonus 30% total Elemental Resistance Optional affixes: #% increased Rarity of Items found +# to maximum Life #% increased Cast Speed
(Belt) Rare Belt - mainly a stat‑fixing slot, helping you cap res, meet attribute requirements, and boost your effective HP pool.
Min. requirements: +20 to Strength +100 to maximum Life +50% total Elemental Resistance Optional affixes: +# maximum Mana #% increased Charm Charges gained
(Body Armour) Rare Armour - look for a high amount of Energy Shield and Resistances.
Min. requirements: +500 to Energy Shield +40% total Elemental Resistance Optional affixes: +# to Intelligence #% increased Rarity of Items found
(Gloves) Nightscale - boosts your crit chance and the unique mana mechanic is perfect for this build - once you crit (which happens constantly), you gain massive mana regeneration, ensuring smooth skill uptime. As long as your crits keep flowing, these gloves feel like a natural fit for the build.
(60—100)% increased Energy Shield (30—50)% increased Critical Hit Chance +(10—20) to Intelligence +(20—30)% to Cold Resistance 150% increased Mana Regeneration Rate if you've dealt a Critical Hit Recently Cannot Regenerate Mana if you haven't dealt a Critical Hit Recently
(Boots) Rare Boots - your Boots should grant you tons of Movement Speed and Resistance. Use your Rune Slot for Rune of the Chase if you have enough Resistances.
Min. requirements: 30% increased Movement Speed +120 to Energy Shield +40% total Elemental Resistance Optional affixes: % increased Rarity of Items found +# to Intelligence
(Jewel) Rare Jewel - one of your main sources of critical modifiers in this build, and each one you socket should ideally carry two separate rolls of Critical Damage Bonus. Since you run many jewels, stacking these double‑crit rolls across all of them results in a massive, scalable boost to your overall DPS.
Min. requirements: #% increased Critical Damage Bonus #% increased Critical Spell Damage Bonus Optional affixes: #% increased Spell Damage #% increased maximum Energy Shield #% increased faster start of Energy Shield Recharge
