I'm trying to come up with cost rules for an item but I'm having an incredibly hard time sorting out how to create the item for 3.5
The item is a cursed item, a badge that was supposed enable the wearer to cast Cure Critical Wounds ten times per day as a 20th level spellcaster but the process went wrong and created an item that will only allow the wearer to cast Inflict Critical Wounds 10 times per day as a 20th level spellcaster and only on the wearer.
I'm trying to figure out a base cost for the non-cursed item and price adjustments for the cursed item.
Any ideas?
