Soulbound

From publisher blurb: The soulbound is a wildly ambitious new class for 5th Edition that allows for unprecedented customization. Soulbound are individuals who've come into contact with a cursed artifact that's merged with them, irrevocably altering their physiology and psyche to form a new entity that's not altogether humanoid. When creating a soulbound, the player picks two different subtypes that relate to a) the nature and origin of their cursed artifact, and b) its type and function when manifested for use in combat. Each of these two key decisions has a massive impact on the starting features of a soulbound and its progression throughout the game. Moreover, when creating a soulbound, the player has unparalleled opportunity to invoke their own creativity and define for themselves the feel and flavor of how their cursed artifact manifests. This iteration of the soulbound, Version 1.0, provides 5 Artifact Origins and 5 Artifact Types–allowing for 25 vastly different permutations of the class from a mechanical standpoint, whilst also allowing for unlimited roleplaying opportunities.
