Boost

Boost is a mechanic that allows you to recover all of your meter at the cost of 1 Spirit Diamond in the player's Spirit Grid.

Mechanics
When the player presses the Z key, they can unleash a non-damaging shockwave that knocks foes back and immediately enter the Boost state, recovering all of their meter and giving the player attack, defense, and speed buffs. (multiplied by 1.25, in the case of defense, divided by 1.25 if the value is greater than 1). Entering the Boost state costs 1 diamond in the player's Spirit Grid. The Boost state lasts for exactly 1 minute. (This is subject to change) In addition, the player cannot gain meter through any other ways besides Items on the battlefield. If the player presses Z again, they will enter the Awakening state.

Trivia

 * The Boost and Awakening mechanics are inspired by certain mechanics from the Naruto: Ultimate Ninja Storm games.
 * The Boost mechanic in particular is inspired from the Demon Slayer: Kimetsu No Yaiba: The Hinokami Chronicles game, where a similar mechanic with the same name is utilized.
