Tiamat

These warlocks are followers of Tiamat

Draconic Pressence

Starting at 1st level, Tiamat grants you the awe-inspiring presence of dragons. You can use your action to exude an aura of draconic majesty. Each creature of your choice within 10 feet of you must succeed on a Wisdom saving throw against your warlock spell save DC or become frightened for 1 minute. A frightened creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. Once you use this feature, you can't use it again until you finish a short or long rest.

Draconic Familiar

When you choose the Pact of the Chain, your familiar can take the form of a pseudodragon. Additionally, when you summon your familiar, you can choose for it to have resistance to one damage type: acid, cold, fire, lightning, or poison.

Chromatic Blast

Prerequisite: Eldritch Blast cantrip

When you cast Eldritch Blast, you can change the damage type of each beam to acid, cold, fire, lightning, or poison. You can change the damage type of each beam individually.

Chromatic Resilience

At 6th level, you gain resistance to one of the following damage types: acid, cold, fire, lightning, or poison. You can change your choice whenever you finish a short or long rest.

Dragon Wings

At 10th level, you can use a bonus action to manifest a pair of spectral dragon wings from your back, gaining a flying speed of 60 feet. These wings last for 1 hour or until you dismiss them as a bonus action. Once you use this feature, you can't use it again until you finish a short or long rest.

Draconic Toughness

Your hit point maximum increases by an amount equal to your warlock level. Whenever you gain a warlock level thereafter, your hit point maximum increases by an additional 1 hit point.

Frightful Pressence

Prerequisite: 10th level

You can use your action to terrify foes. Each creature of your choice within 30 feet of you must succeed on a Wisdom saving throw against your warlock spell save DC or be frightened for 1 minute. A frightened creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. Once you use this invocation, you can't use it again until you finish a short or long rest.

Chromatic Mastery

Starting at 14th level, Tiamat's power flows through you, allowing you to wield the devastating breath weapons of dragons. As an action, you can unleash a devastating breath weapon in a 60-foot cone. Choose one of the following damage types: acid, cold, fire, lightning, or poison. Each creature in the area must make a Dexterity saving throw against your warlock spell save DC, taking 10d6 damage of the chosen type on a failed save, or half as much damage on a successful one. Once you use this feature, you can't use it again until you finish a long rest.
