A nightmarish vision of hatred, rage, and might writhes into view. Five heads, each the color of a different chromatic dragon, spear you With their terrible gazes, momentarily shocking you into stillness as you take stock of the rest of the terrible creature. Beyond five sinuous necks is the creature's powerful and thickly scaled body, wings the size of ships' sails, and a long tail that ends in a scorpionlike barb.
The Dragon Queen uses her aspects to deliver messages of her divine will and wreak unholy revenge upon those who foil her plots. Powerful clerics of Tiamat can call upon her aid in the form of an aspect, but she grants this honor only to those who honor her appropriately in return.
Aspects of Tiamat speak Abyssal, Common, Draconic, Giant, Goblin, and Infernal.
An aspect of Tiamat uses one of its breath weapons (typically, acid) in the first round, and then closes with foes to bring its full attack to bear. If necessary, it flies closer to its enemies and uses its crush attack on one foe. When it can make a full attack, the aspect often bites one opponent and uses its tail on another. When one victim falls, the aspect attacks the other (using its Cleave teat), hoping to gain another Cleave attack after slaying that foe as well.
Breath Weapon (Su): 40-ft. cone or line; each head once every 1d4 rounds; 12d8 damage acid, cold, electricity, or fire; Reflex DC 24 half. Each of the aspect’s five heads can produce a breath weapon, but only one head can do so in any single round.
Crush (Ex): Area 15 ft. by 15 ft.; Small or smaller opponents take 2d8+16 points of bludgeoning damage and must succeed on a DC 24 Reflex save or be pinned.
Poison (Ex): Injury, Fortitude DC 24, initial and secondary damage 1d8 Con. The save DC is Constitution-based.
