I like to tweak my monsters to make them a bit tougher for my PC. I’m looking at moltenwing and seeing that he’s the kind of dragon that doesn’t get out much; I decide to change some of his flying orientated feats to something a bit more martial. Looking through the Draconomicon feat list I come across some really great choices. I’m thinking of switching out wingover and flyby attack for snatch and improved maneuverability. Would anyone else have any suggestions? What have others done to change Moltenwing?
PS: If I wanted a TPK in one round I would sub in Heighten Breath and Shape Breath. With this combo I would have a 50-ft cone of Disintegrate with a DC 34. Just surprise the PC before they have a chance to spread out and BAMB!! little piles of PC dust. If there are any PC left over (and they don’t run), I’m pretty sure moltenwing can handle them while he waits the 7 to 11 rounds for his breath weapon to recharge.
Don't remember exactly the feats he got but you can go for Improved natural attack, maybe the Power attack way with Improved Sunder, Improved Bull rush (in the lava!)or some from Savage Species, Improved natural armor...
