uh, i know we are not supposed to rely on the damage bar indicators and everything, but the max damage and speed on both appears to be identical. the only difference appears to be that the leviathan starts off at a higher damage level, and has an extra star associated with it.
i imagine there is a larger difference, but doesn't that seem odd? maybe its a bug. they're all bugs. :/
Good question. All the more important after the whole "Cold Iron Carver doesn't do hooey" debacle.
