A monster with the Morph ability can choose which dice it attacks with. For each morph die (indicated by a die icon with a question mark) the monster has on its reference card, its player may choose a red, white, blue, yellow, or green die to roll, limited only by the dice that came with the game. The attack must include at least one red, white, or blue die, but can include more than one of those dice if so desired. The overlord also chooses what kind of attack the creature makes (melee, ranged, or magic), save that the attack must include a red die to be a melee attack, a blue die to be a ranged attack, or a white die to be a magic attack.
