Nice icon there!
Giant icons are always nice to have.
Maybe it could breathe boiling water or something...
Hmm - I would like to give breath weapons to my dragons as well, but I don't think that is possible yet, either, right? (Not sure how to even do any cone-based spells, actually, since unlike circle-based areas, I can't just draw one big animated effect for cones - since I can't guess what direction it would be blasted from...)
(Also, nope, no underwater dragons in AD&D, but some dragons could breathe water automatically... like golds, I think.)
