I am writing a build guide for the Elemental Commixture teamwork feat.
I am looking into having a Valet Familiar cast the secondary spell. I know this would work with the metamagic Familiar Spell but this is not worth doing. Instead I want to have the familiar cast the secondary spell from a wand or scroll. I'm not sure whether that would be allowed for Elemental Commixture.
When I cast from a wand or a scroll, am I casting the spell or is the item casting the spell?
You and an ally within 30 feet who shares this feat can cast your spells together to create a more powerful, hybrid effect. ... When the spells to be commixed are cast, one is designated as the primary spell (typically the higherlevel spell), while the other is the secondary spell. The primary spell must be an offensive spell that targets an area or one or more creatures. The secondary spell can be any spell with an appropriate descriptor. Neither spell can take more than a standard action to cast.
Spell Completion: This is the activation method for scrolls. A scroll is a spell that is mostly finished. The preparation is done for the caster, so no preparation time is needed beforehand as with normal spellcasting. All that’s left to do is perform the finishing parts of the spellcasting (the final gestures, words, and so on). To use a spell completion item safely, a character must be of high enough level in the right class to cast the spell already. If he can’t already cast the spell, there’s a chance he’ll make a mistake. Activating a spell completion item is a standard action (or the spell’s casting time, whichever is longer) and provokes attacks of opportunity exactly as casting a spell does.
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.
Wands use the spell trigger activation method.
