Many wondrous items and other equipment duplicate spell effects, typically at the Caster Level the item itself. I would be interested in making a character that used their own HD/Class Level/Caster Level in place of such magic items.
Mask of the Skull, 1/day CL 13 effect of Finger of Death. I think a really cool build would allow me to use this (and other 1-3 use per day magic items) at my current character level, so that at 15th level, Mask of the Skull would do 150 damage or save for 3d6+15.
Ideally, this would be a non-caster type because otherwise I'd just as likely make a Wizard with Staff-Like Wand. I'm not looking for tons of magical spellcasting, but to actually benefit more than just minimum CL items (without dealing with getting a GM to allow me to pay more for higher CL Wondrous Items).
Paizo material preferred, 3pp content allowed, no 3.5.
