Since DnD is going down it's more corrupt path I figured I'd flex my creative muscles to see if I could make a concept similar to a Lich without making it an outright Lich.
In my game system or world more of the fact magic and spirit is separate so warlocks aren't given spells but their patron or contractor channels spiritual energy through their body; the spirit aspect being that in exchange for power you have a limited amount of divine favors you can call upon a day.
While casters under my system can know a lot of spells but have a physical limit to their body without overworking it or having it study even further how to reduce the need to brute force the spells to cast or in general be smarter with what kind of spells they cast.
Soul Pyre fall under this idea of spirit but instead of calling upon divine favors, they're burning through souls instead. I explain more in the blog but basically all of their divine power comes from burning through strong souls so you can guess what Soul Pyres target, that being monks, warlocks, priest, etc.
Feedback on such a monster idea would be great.
