The Dragon Queen

Tiamat is the patron goddess of chromatic dragons and the embodiment of greed and envy. Tiamat is a unique chromatic dragon, who had one head for each primary color of the most common species of chromatics (black, blue, green, red, white). She is the creator of the five primary species of chromatic dragon, each taking the form of one of her heads. Tiamat combines the powers of all of the chromatic dragons.  The Dark Lady appears to be a humanoid female with long dark hair and completely black eyes. She always wears dark robes and usually had a seductive smile on her face. The benefits of the pact grant you access to more weapons and armor, defensive abilities, and control of chromatic damage. In return you must give tribute to Tiamat, in the form of silver or pearls, emeralds, garnets or rubies, blue quartz or blue sapphires, obsidian or onyx, and blood stones.

The Queens Warrior

You gain proficiency in medium armor, shields, and martial weapons. Additionally your pact grants you either a shield or a weapon embossed with her symbol (five chromatic dragon heads forming a pinwheel).

Dragons Rage

Starting at 6th level, your patron grants you the power of a dragons rage. You can enhance your spells to eliminate the life force from creatures. You have a pool of energy represented by a # of d10's equal to your spell caster level. When you roll damage for a spell, you can increase that damage by spending the dice from the pool. Roll the spent dice and add them to the damage as (fire, cold, acid, lighting, or poison) damage.

Dragon Tail Defense

When you are wielding a piercing or bludgeoning weapon with which you are proficient and a enemy hits you with a melee attack, you can use your reaction to add your weapon proficiency bonus to your AC for that attack.

Chromatic Master

Starting at 14th level you gain resistance to acid, cold, fire, lightning, and poison damage, as well as immunity to being frightened.
