I was going over the specs for one of my potential characters and I love the spell Enlarge Person. It's insane. As a Cleric under Cayden Cailean, my character can use that spell, but a standard Cleric wouldn't be able to. The question is: can my character use a wand of Enlarge Person?
It's on your personal spell list, so yeah
Any spell your class has access to, or that you can cast natively, you can use a wand of (except in specific cases that call out the lack of availability, such as specialist wizard). Of course, you can always make a Use Magic Device check to try and use the wand even if you can't use it normally.
From the Wand entry:
From the Spell Trigger entry:
Note that strictly speaking, by the above wording, you can use wands of anyone's domain spells. I do not suggest trying this, as you may get hit by the book.
