The "Leadership" quality possessed by Storm and Cyclops can be a tremendous asset to the team. This skill multiplies both damage and experience when successfully completing a combo. At its highest level Leadership will multiply damage by 150% and experience by 25%. Use Storm and Cyclops together to multiply these values a second time. That's 625 damage of a base 100 attack. With a good roll of the die, combo attacks upwards of 1500 are possible by the end of the game.
