Booster (ブースト Būsuto?, lit. "Boost") are a set of items in Kingdom Hearts Unchained χ / Union χ which increase damage dealt by specific Medals.

Mechanics

Boosters are only in effect for a limited time. However, instead of having a duration of effect, Boosters have a set expiration date. Boosters can be obtained from certain Events, and take effect as soon as the Player obtains them. Stacking multiple of the same Boosters is possible.
