Oomph is one of Hero's Down Special Moves available from Command Selection. Hero temporarily increases the power of his melee attacks for a short time.
Overview[]
Oomph has an MP cost of 16, and when cast Hero will raise his sword in the air and emit an orange aura around himself. For twelve seconds off all of Hero's melee attacks deals 1.6x damage and 1.1x knockback, making him an effective damage and knockback dealer at the expense of taking 1.2x more damage, making it very similar to Shulk's Buster Monado Art. The increased damage output also enables Hero to regain MP quicker.
