I might be playing a spellweaver in the next campaign and i need help figuring out how to give it more arms.... grillions blessing gives it two more but i would love to find something more permanent. Any sugestions?
Insectile template from savage species adds 4 arms I believe, I am not sure if the spell weaver qualifies.
The same book has the vest of the naga (something like that) which is a vest that adds 2 arms. I like to build in the Arms of Nyr if you are good into the suit to add a +2 Str and +2 Dex unlisted (Found in defenders of the faith).
The Spell battle arms from dragon magazine adds up to 4 arms and gives you full BAB, but it is a cleric/blackguard level 4 spell.
There is another wizards spells some place called extra arms, which does the exact same thing as grillions blessing, but is a different spell.
Your best bet is probably the magic item since it will run 24/7.
