While raging, a barbarian cannot use any Charisma-, Dexterity-, or Intelligence-based skills (except for Balance, Escape Artist, Intimidate, and Ride), the Concentration skill, or any abilities that require patience or concentration, nor can he cast spells or activate magic items that require a command word, a spell trigger (such as a wand), or spell completion (such as a scroll) to function.
I would really like to activate a wand while raging, but as far as I can tell, there is no feature out there that lets you.
Rage mage doesn’t; spell rage allows spellcasting, but not magic item use. Righteous Wrath also fails to do it, at least explicitly; Righteous Wrath actually kind of fails to do anything at all despite the description, since the only things it explicitly allows are things raging never caused a problem with in the first place.
So, without making assumptions about Righteous Wrath being interpreted generously, does anyone know of a way to activate a spell-trigger item while raging? Tricks to exit the rage and re-enter it are not answers; I want to cast the item’s spell while raging.
E6 is preferred; Epic is not allowed at all. Otherwise, any Wizards-of-the-Coast-published 3.5e materials, as well as 3.5e issues of Dragon and Dungeon, are acceptable. Third-party material, regardless of its licensing status, and homebrew material, regardless of its quality, are not acceptable (I am already aware of options that fit the bill from those categories; the point of this question is to avoid that). The form of the option doesn’t matter: feat, class feature, magic item, spell, whatever. I’d prefer not to have to multiclass for it but if that’s a way to do it, I want to know.
I’m not really looking for shenanigans; I’m hoping to find something that just says “you can use spell-trigger items in a rage.” I may accept RAW shenanigans, but only if they’re particularly air-tight and require neither DM assistance out-of-character, nor NPC assistance in-character. In short, please avoid anything that starts going “ask your DM to accept this dubious interpretation that might be there, if you squint.” Greater uses of wish and stuff like that are right out.
