AK Starter Guide - for your first trip through
Viable Repose/Sleep targets
Human clerics.
Gargoyles, from statues.
Hound lights (casters; careful).
Smolenkos (Ahriman).
Noteworthy enemies
Dullahan: will buff itself over time for heavy damage. Do not be in front of. Regen early; Cure2 may be needed, particularly for WARs.
Succubus: Doesn't link to other mobs (though others link to the Succubus). Can be pulled separately in each case, though range can be tricky. Uses Void Thunder 3; can LOS by walking through her.
Bosses
#1: Beat on priest to summon main boss. Have Void Thunder 3 interrupted every time; 2.5k damage per cast otherwise. Regen/Cure to beat Mind Melt's AOE dmg. Canker will lay on Disease; Esuna fixes. Adds spawn; watch threat & ground effects. Stay at edges of the room to avoid giant golem attacks after mid-phase. Can LOS boss spells with a pillar, if you're feeling punchy.
Tank can walk through boss to LOS Void Thunder 3. Tank can probably stun every Mind Melt, if they wanted.
