Spirit Keep guide: beat the Spirit Guardian with Heal Reduction

The Spirit Keep is where you farm the Lesser, Greater and Superior Spirit Potions needed to Ascend Spirit Affinity champions. Ascending gives extra base stats, unlocks Amulets and Banners at the required Ascension Levels, and can improve certain skills, such as unlocking passives. Here is how the boss works and how to build for it.

When it opens

The Keep is normally available twice per week, on Mondays and Thursdays. You can open it on other days for 200 Gems, but that is a last resort, for example if missing Potions would stop you Ascending the Epics you need before a Fusion deadline.

Aim for the highest stage you can clear consistently, eventually Stage 20. At that stage Lesser Potions drop out of the reward pool, so if you still need them for lower rarity champions, drop back to an earlier stage.

The Spirit Guardian's skills

• Melt hits all enemies, and hits harder the more HP she has. Decrease ATK, Increase DEF, Shields and healing help, and so does burning her HP down quickly.
• Cleansing Spring removes all her debuffs and gives her Block Debuffs for 2 turns. Remove Buffs or Steal Buffs strips it so you can reapply Heal Reduction.
• Revitalize is the passive that matters: she heals 50% of her MAX HP at the start of every turn. 100% Heal Reduction stops it completely while the debuff lasts.
• Almighty Immunity makes her immune to most crowd control, including Stun, Freeze, Sleep, Provoke, Fear and Block Active Skills. She is also immune to HP exchange, HP balancing and cooldown increasing effects.

She can still be hit by Decrease SPD, Turn Meter reduction and Heal Reduction. With enough Speed and Turn Meter control plus damage, you can kill her before she takes a turn, which avoids both the healing and the cleanse.

Waves and minions

You clear two waves before the boss. Seer or Poison Explosion style teams tear through them quickly. The boss also brings two minions: the left one can Stun, and the right one applies Decrease ACC, which threatens your Heal Reduction. Kill or control them, or bring Block Debuffs or Remove Debuffs.

Team roles

The guide's example Stage 20 team is:

• Venomage: holds her A3 until the boss phase, where it places Heal Reduction and Poisons together. Her A1 adds Decrease DEF, Decrease ATK and Poison activation.
• Dorothy: can remove or steal buffs to break Block Debuffs, and her A2 adds Decrease DEF and Decrease ACC.
• Visix: brings Decrease SPD, Provoke, a Shield, and a chance to reduce Turn Meter by 15% per hit with her A1.
• Xenomorph: uses Infest to melt the waves and stacks Poisons for boss damage.
• Michelangelo: adds AoE Decrease ATK, Leech, Decrease DEF, debuff spreading and Stun on his first target.

Building them

For the champions placing Heal Reduction, removing buffs or cutting Turn Meter, aim for around 25 more ACC than the boss's RES. Check your stage in the Raid Stages Tool. Magic champions are at an Affinity disadvantage here and can land Weak Hits, which stops debuffs attached to attacks, though placement skills that need no attack are fine.

Perception, Pinpoint, Feral and Accuracy sets help reach the ACC you need. Reflex and Relentless give extra skill reuse, while damage dealers can take Savage, Merciless or Lethal. SPD helps keep Heal Reduction up and cycle back to buff removal.
