So far Medusa has two abilities, petrify and the toxic pool, but IMO, maybe she should have a third ability? Both the Magikill and V have three abilities, and I think it's just right for Medusa to have a third? Since she is like the "big character" of chaos?
I was thinking of maybe a direct damaging attack from he snakes, attacks in an area, and deals AOE damage with stun? Maybe called snake swarm? It would defiantly be helpful in battles, and maybe make her more competitive against other spell casters? Let's face it, Petrify is deadly, but can't really kill every unit outright and it also has a long cool down, and the toxic ability is more like a supporting attack. A more easily used direct striking attack that deals AOE damage and stuns would help I think.
