• Drowned Sailor, a pale corpse with rubbery flesh falling from the bone, wielding a rusted saber in one hand and a flintlock in the other.
• Coral Husk, Jagged coral fused to the very bone, these husks are hard as stone and use their bodies as a weapon while taking little damage due to their harden coral.
• Shadow of the Deep, the murky shadows of the drowned their bodies like a murky ooze of shadow and sea water, able to move through the shadows an attack from blind spots.
• Barnacle Knight, once loyal sailors who were Keelhauled for treachery and betrayal, now covered in barnacles acting as armor, eternally loyal in death, like the Coral husk their bodies act as natural armor and weapons,

Whenever one dies:

• Kael"Thrain gains 5 temporary HP
