So who's that little guy that hangs out in the upper part of the battle screen anyway?
That, my friends, is a Dilla. Dilla are helpless little Monsters. They have no battle prowess, no special moves and just enjoy laying about. Looking into a Dilla's eyes, they are quite vacant!
They also come in a variety of colors and patterns.
A Monster without special abilities? Why would you want to carry one around? Well, as you build synergy you may find yourself in a position where you must take a hit. In that situation, you could send out your Dilla, absorbing a hit and vanishing for the rest of the battle.
Some Dilla, upon getting hit can even release energy that inflicts status effects, lowers stats, etc. of the enemy Monster.
