Waiter, one "Illiterate" tag for our esteemed murderhobo.The former includes restrictions where they are meaningful component of character, faction or spell/item concept - those can be replaced by specific ethos (which is much easier to track mechanically due to being spelled out) - and things like protection from evil, which can be easily patched up by more specific targetted spells like protection from lower planes (analogous to protection from undead and its ilk).
So, instead of casting one protection from evil, a guy has to cast protection from lower planes, protection from undead, protection from nasty elemental thingies, protection from selfish humanoids, protection from selfish non-humanoids, protection from... wait, i run out of slots, did I say that vancian magic is also bad?
