How to beat Kin Priest
- You have two viable approaches: (1) Kill the followers first to reduce incoming damage, then focus the Priest, or (2) rush the Priest directly — killing it ends the fight instantly. Option 2 is faster but riskier since you’ll take unblocked follower damage. AoE damage is strong here since it hits all three targets.
- Killing the Kin Priest ends the fight immediately — followers disappear
- AoE attacks are very effective in this three-target fight
- Followers are staggered — one attacks while the other buffs, so there’s always incoming damage
- Artifact or debuff removal helps counter the Frail/Weak cycle
