The recipient of this spell grows an extra pair of arms. These arms hinder the creature in no way, but the creature has no control over them either.
When the creature is attacked by a metal melee weapon, the hands make a touch attack (using the BAB and Int bonus of the caster) against the weapon. If the touch hits, the weapon melts immediately. If it is a magic weapon, it gets a fortitude safe against this effect.
The spell has 1d4 charges, and once the charges are gone, the spell ends. Charges are expended when the hands attack, wether the attack hits or not, or the weapons makes the safe, the charge is gone.
