You should reconsider his Trample. As it is, your Deep Dagon will never attack anything smaller than size 6 with his normal attacks, and he has only 6 AP so he won't be able to trample more than a few enemies.

I'm not sure if he's balanced or not. All that hp, prot and strength is frightening, but his attack, defense and mapmove really suck. Underwater, he's insane, but R'lyeh is underwater and doesn't really care about his elemental immunities, and his magic resistance isn't any higher than other pretenders'.
