With a good third skill to keep this hero alive you can let Banshees take L6 carrion and live, targetting units/allies while this hero is alive will not do very much for you so it's beyond vital to kill him immediately if you want your damage to be worth it, early on AoEs massacre him despite his high strength, once he has some way to stay healthy and alive though L6 protection means you must kill him immediately. If you L3 Yamato an allied hero of his at this point if the hero's armor was 0 both them and Captain Obvious would take 150 damage. Target the helpful idiot before he becomes too big a threat. On his own he's actually fairly harmless, but with things to deal damage he becomes very good.

The Dream Eater has absolutely terrible stats, is slow, and without items can't effectively use their skills often at all. However it's more than capable of disemboweling threats safely provided it can get the mana to do so and avoid dying in the process.
