Shroud of the Aether

This roleplaying game supplement introduces a ghost casualty class for characters who die but continue adventuring as undead. The class combines ghost abilities with hit dice, attack progression, and saving throw progression, allowing a character to remain involved until being raised, reincarnated, or permanently transformed. It includes general ghost feats and feat chains focused on aetheric movement, banshee abilities, telekinesis, corruption, dread, and malevolence, along with a glossary of relevant SRD rules for reference.
