Item Boost

Item Boost is an ability in Kingdom Hearts II, which increases the effect of all recovery items used on the field (i.e., Potions, Ethers, Elixirs, etc.). It can be learned at a different level depending on the "style" Roxas chose (Sword, Shield, or Staff), is equipped on the Monochrome Keyblade, and other party members also have it. This ability costs 2 AP.
