Final Effort is a technique used by Piccolo and Vegeta, that exerts chi in a circular radius away from the user and destroying everything in that field. When fighting Boo, Vegeta used a maximized power version of the technique that exerted so much energy, it left him a lifeless husk in the aftermath. Piccolo also used an extreme version of the technique after much charging to completely level Papaya Island.

This HTB skill features Final Effort as the culmination of the attack, following a Turtle Rod attack combo and something that resembles the Kamehameha. It is learn-able from level 40 by Turtle Hermits.
