Thundergauntlet
Power Point Abilities
Thunderclap (1 PP) As a standard action, the mech can use a thundergauntlet as though it were a ranged weapon with the blast weapon special property and a 30-foot range. If the mech has two thundergauntlets, it can use both as part of this attack to deal medium damage rather than low damage; use the average of the two thundergauntlets’ levels (rounded down) to calculate this damage.
This glove-like weapon emits piercing shrieks that can disrupt opponents’ basic movement and functionality.
