Robes

Robes is a Boneyard undead enemy with a deceptive lifecycle: it fires an infinite-range attack that inflicts Leech 1 and can summon Wisps during combat, but defeating it only triggers its true form — Robes transforms into a Tatters upon death, forcing players to contend with a second enemy phase. It relies entirely on shield for defense with only 4 HP behind 6 shield, so shield-piercing attacks sidestep its durability entirely.
