Attack pattern
A dragon always attacks first with its breath weapon, then either breathes again or makes melee attacks (equal chance of either).

Can be used up to three times per day. All caught in the area suffer damage equal to the dragon's current hit points (save versus breath for half). Shapes of breath weapon:
Special

Special
Cone
2' wide at the mouth, 30' wide at far end.
