Fist of Corruption: This pitted, rust stained iron gauntlet looks like it is about to fall apart. When worn over the hand, however it feels solid and comfortable and well oiled. The back of the gauntlets is decorated with a raised image of a harpy with a wizened, aged face.
On the plates above the wrist are three command words.
The first allows you to launch an acid arrow, as if cast by a 3rd level caster, three times per day.
The second allows you to use rusting grasp once per day, as if cast by a 7th level caster.
The third allows you to cast acid splash as a standard action.
