Goodness, Spell Devourer kinda eats Consume Spell's lunch (punintended). Sure, the latter is real healing rather than temp HP that lasts a round, but it's also much harder to actually get the benefit from.
Thank you. I was sure it worked from abilities with any of the magical tradition traits but at the same time didn't make that much sense, since they weren't really spell-like abilities from past versions of ttrpgs.
