As a bloodrager has few spells per day and (as I understand him) can only cast while raging I felt that an item storing spells would be good.
But which spells would you store in a ring of spell storing or (which is the only thing I'll have for now) a cracked Vibrant Purple Prism which works like a minor ring of spell storing that can store one spell level.
I could use it for a spell I can cast myself and use often, I could buy a wand and use that to charge the ioun stone or I could or I could hope to find some nice arcane caster that fills the stone for me. But again, with what spells?
My first idea was to ask another caster to charge it up with detect magic and another cantrip so I can use those when I need them. But is this worth it?
My second Idea was to have it charged with feather fall, because if I really can't cast without raging this spell would be silly for me. But the ioun stone has a minimum casting time of 1 standerd action.
So apart from using it to take an unused spell slot from one day to the next, what can I do with it that's worth it?
We will start our playtest game at level 5, if that's relevant to the topic at hand.
Thanks.
To answer the original question, I've enjoyed having a dagger of Cure Serious Wounds on my person while playing Witch. Not because it was particularly powerful, but because it's satisfying to stab The Waste of Space when they need yet another lifesaving heal in between dealing two damage each round. Also fit my character as sadistic high-functioning sociopath.
As a bloodrager, I could see Bungle being quite interesting at low levels. Once you hit the 10 HD cap it's useless, but until then it's effectively a free action Will-or-Lose-your-next-turn against martials and concentrating casters. Once you get 2nd-level spells, upgrade to Oppressive Boredom for an actual Will-or-Lose-your-next-turn. Good 3rd levels are Unaldulterated Loathing, Vampiric Touch, Dispel Magic, or any of the targeted damage-dealing spells (if damage is your cup of tea, anyways).
Edit: Forgot for a moment that Bloodrager has magus spell list, not sor/wiz. Whoops.
As I didn't find useful spells I didn't include the ioun stone in my equip and now we already started. But I'll keep it in mind for when I get another chance to play one.
BTW the spell list isn't that important. I could buy a wand and have a wiz/sor charge my ioun stone between combats.
I think frigid touch is a Nice spell to have in a Spell storing weapon or Armor.
