Aye, Dragon-Spawn, and this is without mentioning that the mighty Vilemaw possesses numerous special abilities, rather than simply blowing minute spurts of flame at its foes. I approve greatly of the remake to this Field of Justice, particularly the new weapons that are to be made available (also courtesy of the Shadow Isles).
Edit: From further browsing of the map itself, an additional discovery has come to light: the skeleton of a comparatively tiny dragon tangled in the webs of Vilemaw. Vilemaw further brings a toxic corrosion ability, reducing its targets' armor and magic resistance, while also being capable of pulling in its victims with a large web. A mighty multi-clawed attack also is in its arsenal, rending its foes with crippling blows. Should the beast be defeated (not slain; it explicitly retreats back into its lair), the reworked Crest of Crushing Wrath bestows rapid replenishment of its bearer's health and mana, increases the speed at which they attack, and reduces the cooldowns of their spells. 'tis clearly a worthy investment of time.
