New rarity: The equipment is boring, pretty much just giving everyone more health.
Shield guy: He directly counters Medusa (who no longer needs a counter, archer and wee witch. Otherwise, pretty boring.
Sorceress: Her (hidden) skill description says she reduces skill levels, making her the counter to DM and Cyclops. Otherwise, nothing special, but this one ability might make her a game-changer.
Karaoke King: Completely broken, mixing the best abilities of other characters. His white seems the same as Wolf's, but better. His blue makes him immune to magic damage (just what we need - a new Spectral). His green is a heal. His purple is a slow, like Kraken's. This guy will be the new hero who must be on every team, because who wouldn't want an even better Wolf? Oh, and his legendary (if it's ever released) boosts expertise, making him even more ridiculous.
