Frage steht oben, es geht natürlich um den Attributswert, um den Zauber überhaupt wirken zu können. (Also 10+Zaubergrad bei Weisheit/Intelligenz/Charisma)
Hier mal die entsprechenden Regelteile:
Spell Trigger: Spell trigger activation is similar to spell completion, but it's even simpler. No gestures or spell finishing is needed, just a special knowledge of spellcasting that an appropriate character would know, and a single word that must be spoken. Spell trigger items can be used by anyone whose class can cast the corresponding spell. This is the case even for a character who can't actually cast spells, such as a 3rd-level paladin. The user must still determine what spell is stored in the item before she can activate it. Activating a spell trigger item is a standard action and does not provoke attacks of opportunity.
Ich denke, unter den fett markierten Bereich könnte man es einordnen. Was mich aber stutzig macht, ist...
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.
Hier werden explizit Schriftrollen erwähnt.
Use a Wand, Staff, or Other Spell Trigger Item: Normally, to use a wand, you must have the wand's spell on your class spell list. This use of the skill allows you to use a wand as if you had a particular spell on your class spell list. Failing the roll does not expend a charge.
Hier wird das Thema Ability Score überhaupt nicht angekratzt.
Ich finde, das ist nicht ganz genau erfassbar, würde aber sagen:
RAW: Diskutabel (gab auch neulich das Thema am Spieltisch, wir kamen zu keinem festen Ergebnis)
RAI: Nein
Übersehe ich da irgendeine Passage, die das Ganze eindeutiger macht? Interpretiert ihr das anders?
