The Bigby's clenched fist spell brings forth a huge, disembodied hand that is balled into a fist. This magical member is under the mental control of the spellcaster, who can cause it to strike one opponent each round. No concentration is required once the spell is cast. The clenched fist never misses, but it can only strike as directed by the caster. Thus, it can be fooled by invisibility or other methods of concealment and misdirection. The effectiveness of its blows varies from round to round.
The fist has an Armor Class of 0, and is destroyed by damage equal to the hit points of its caster at full health.
The material component of this spell is a leather glove and a small device (similar to brass knuckles) consisting of four rings joined so as to form a slightly curved line, with an \"I\" upon which the bottoms of the rings rest. The device must be fashioned of an alloy of copper and zinc.
