I think you can achieve more vit on crafted items (vit + all attributes combined), but max resistences are nothing to fuck with.
Also, rathma's staff is so rad I might as well use it on a sorcerer when I'll have such option bcs rare items SUCK huge dildo in tchernobog. Yes I am pissed.
in my opinion guardian recipies will be better than ritualist recipies.
ritualist recipies will adds vit stat and page 6 spells but level of page 6 spells are not important than page 5 to 1.
guardian recipies will adds vit stat and AC.
