Void Keep — guide

In short

Void Keep is the Void potion dungeon: it drops the potions you need to ascend Void champions. It is open only on Sundays, so plan your energy and refills around that. The boss does not hit hard, but he buries your team in poisons while two side minions add extra debuffs — a clean run is about cleansing, not damage.

Mechanics

• Dark Harvest — an attack on the whole team that places two 5% poisons for 3 turns. They cannot be reflected back at the boss, so you defend with cleansing and HP buffer, not with retaliation.
• Agony — the boss's signature mechanic: the poisons sitting on your champions trigger together every few turns for instant damage. That is what wipes teams, not the boss's raw hits.
• Immunities — Stun, Freeze, Sleep, Provoke, Block Active Skills, Fear and True Fear do nothing to him, and neither do HP exchange, HP balance or cooldown increase effects.
• Minions — two adds flank the boss and apply their own annoying debuffs, making cleansing harder. Either burst them down or ignore them if your cleanse already covers the fight.

What your team needs

• Cleanse or Block Debuffs — the mandatory slot. One mass cleanse on a 3–4 turn cooldown shuts Agony down almost completely.
• Decrease DEF and Weaken — without them the fight drags, and the longer it drags, the more poison stacks you carry.
• Accuracy — around 200–250 on your debuffers, otherwise Decrease DEF simply does not land and your damage collapses.
• Speed and survivability — roughly 180–220 SPD on support so the cleanse keeps pace, plus enough HP/DEF to eat the AoE and the poison tick.
• Healing and revive — one reviver makes the run far more forgiving. Block Revive is not needed here.

Teams

• Budget: Deacon Armstrong (lead, turn meter boost, Decrease DEF) + Mausoleum Mage (cleanse and Block Debuffs) + Kael (poisons and damage) + Coldheart (HP-based damage). Mausoleum Mage strips poisons before they tick while the rest burn the boss.
• Mid-game: Deacon Armstrong + Mausoleum Mage + Geomancer (damage and reflect off the AoE) + Fahrakin the Fat (ally attacks, poison, HP burn). Two layers of poison protection plus steady damage.
• Endgame: Mithrala Lifebane (Accuracy aura, Hex) + Siphi the Lost Bride (cleanse, Block Debuffs, revive) + Acrizia (HP-based damage) + Gnut (Decrease DEF, boss damage) + Yumeko (cooldown reset). Cleanse cycles endlessly and the boss folds in a couple of loops.

Common mistakes

• Ignoring poisons and relying on healing — Agony out-damages any healer's output.
• Bringing control (Stun, Freeze, Provoke): the boss is immune, so those slots do nothing.
• Running low Accuracy on your debuffer, so Decrease DEF never lands and the fight stretches until poisons pile up.
• Killing the minions at the cost of boss damage when your cleanse already handles the fight — wasted turns.

Tips

• Set your cleanse to top priority in auto-battle, or the AI will happily skip it.
• Put your damage dealers in Lifesteal or Immortal so the AoE and poisons stop being lethal; support wants Speed, debuffers want Accuracy.
• Masteries matter more than they look: boss-damage nodes shorten the fight, support-tree masteries keep your cleanser alive.
• Relentless and Toxic are solid options on damage dealers once survivability is covered.
• Farm in batches on Sunday — one energy session covering several stages is more efficient than spreading it thin.
