avete dimenticato questo:
Emulate an Ability Score: To cast a spell from a scroll, you need a high score in the appropriate ability (Intelligence for wizard spells, Wisdom for divine spells, or Charisma for sorcerer or bard spells). Your effective ability score (appropriate to the class you’re emulating when you try to cast the spell from the scroll) is your Use Magic Device check result minus 15. If you already have a high enough score in the appropriate ability, you don’t need to make this check.
ergo, se devi lanciare un inc di 9o da mago e non hai int 19, devi fare un check con DC 34.
riassumendo:
decifrare: 25+liv
emulare abilita` (eventualmente): 25+liv
lanciare: 20+liv
