Who can use a wand or other item that is activated with
a spell trigger? I would think that you would have to be
able to cast the stored spell. That is, you must have levels in
a class that can cast the spell, have enough levels in that
class to cast the stored spell, and have an ability score
sufficient to cast that spell. If you’re a fighter with an
Intelligence score of 9, you can’t just pick up a level of
wizard and start using a wand of fireball, can you? Wands
and other spell trigger items are for dedicated spellcasters
who use them to carry around a few extra spells in case
they run out, right? These are not items that allow dabblers
to mimic true spellcasting ability. Still, some of my friends
insist that you can use any spell trigger item (wand or staff)
if you have at least one level in a class that could possibly
cast the spell. They point to the term "spell list" in the
description of spell trigger items in the Dungeon Master’s
Guide. Surely, that refers to the list of spell you can
conceivably cast, not to a class’s entire spell list. After all,
the Dungeon Master’s Guide does not use the term "class
spell list" when talking about spell trigger items. Please
preserve play balance in our local campaign by telling me
that I’m right.
Sorry, but your friends are correct. If you’re a member of a
class that has spellcasting ability, you can use any spell trigger
item that stores a spell that’s on your class’s spell list, even
when you don’t have the class level or the ability score to cast
the stored spell. This even applies when you don’t have enough
class levels to cast any spells at all. For example, a paladin of
1st, 2nd, or 3rd level has not yet gained any spellcasting ability,
but she still can use spell trigger items that store spells on the
paladin class list. If you’re a specialist wizard, spells from your
opposition schools aren’t part of your class spell list, and you
can’t use spell trigger items that store those spells.
