.........ultimate ability you say? big bang kamehameha!!!!!!!!!!!!!!!!!!!!! But seriously, for a Titan, Frenzy. When activated, your Titan gets a protective aura around him or her that lasts for a short period of time. During said time, your Titan's melee ability increases dramatically where most enemies die in one hit. Another ability that would be pretty cool would be for a warlock, Elemental Crush. Pending on what element is in greatest quantity around you, you control that element to deliver punishment to your enemy, be it Earth, wind, fire, or water.
