MP Hastega is a support ability in Kingdom Hearts II and is based on MP Haste though at peak level. This ability recharges the character's MP 100% faster than normal (twice the normal rate). Only two characters can learn this ability, Sora learns this ability from the Ultima Weapon and Donald learns it from his Ultimate Weapon, Save the Queen+. It is also an automatically equipped ability for Sora's Wisdom Form. Auron also has this ability, as do a couple of other World Allies.

In addition, MP Hastega can be used with one or more MP Haste at the same time, accelerating MP recovery even further.
