Boosting is used for leveling up Monsters and increasing their overall stats. Boosting is the only way to increase a monster's power, since Evolution increases the rate at which stats increase as opposed to directly increasing the stats. It is possible to Boost a monster with any other monster, but the best type of monsters for Boosting are Boost Material Monsters which can be found in the Lucky Zone or during Events.
