. . . temporarily, at least:
Full attack: Searing Charge, allowing him to charge attack, in flight, with perfect maneuverability. Not sure how much "flanking" matters with flying creatures, but as I have plenty of movement (120'), Tal will circle up and attack the dragon from whichever direction (most likely above) that gives flanking with others.
Only get the one attack (which is why he doesn't usually charge) but adds fire damage:
claw - (1d20+27)[29] damage - (2d6+16)[26] plus
fire - (5d6)[15] (if it's available and matters, +2 to hit for flanking)
After that, he'll just let himself fall to the ground. The height isn't worth burning a
feather fall. Just let me know how far.
Edit: Wow! What a dangerously-bad to-hit roll that was. Might need the flanking bonus after all.
I'm just not used to flying.
