I don't have the game installed, so could someone test this out for me? I got this from Scythesong's guide on Blades from Sorcerer's Place. You Polymorph Self, than transform into a sword spider.
"The Sword Spider has 5 attacks per round and can poison enemies, and when a dispell magic is cast on a Blade in Sword Spider form the Blade may now use his own weapons in place of the spider's - at 5+ attacks per round (cheesy tactic, but not really necessary)."
This is a well known bug which is active for all forms, however, some forms' special abilities come from their magic weapons, like a Wolfwere's immense regeneration rate so it is best not to dispel some.
If you know how to play though, your original form should be more powerful than any of the Polymorph Self ones.
“The world breaks every one and afterward many are strong at the broken places. But those that will not break it kills. It kills the very good and the very gentle and the very brave impartially.”
