Oh, and as for dealing with Entangle, do unto it, what it does unto you.
Clerics have a spell called Free Action, this will nullify the Entanglement, your mages can also cast Web on the Dragon, then the Dragon becomes immobilised and unable to do anything.
You can still move though, because of Free Action.
Ring of Free Action and Keldorn's armour also have innate Free Action, plus some short sword.
I kinda accidentally used this Web Tactic in my first game, I figured since everybody was entangled, let's share the misery.
------------------
If not a Sorcerer casting total oblivion, then a Paladin meting out justice. Otherwise, I think I will just be a bard and torture my enemies with, "My Heart Will Go On".
