The robot cores introduced in a prior update now have more relevance in the game, and boost the effectiveness of abilities sharing the same type in battle. As an example, Ice Man has a Freeze Core which allows him to both equip Freeze Type abilities and (thanks to this update) deal 25% more damage when using them! This change should make robots without a Copy Core (like Mega Man and Proto Man) more useful in-game and slightly tougher opponents in battle. As always, check the Robot Database for information on which robots have which cores.
