I have a class that, as far as learning the full rules for it, is even more complicated than my Magus class.
It is a spell point blood magic sorcery corruption wizard.

(I actually call it warlock internally, as is mentioned on the page and is also pretty noticeable, but it’s worth mentioning here; it’s not intended to replace the warlock class, my own mental picture of the different synonyms for ‘spellcaster’ just makes this class line up best with ‘warlock’.)
