Tiamat's Chosen

You've somehow brought forth the holy attention of Tiamat. Through direct or indirect contact her chaotic nature has taken hold on you and grows as you do.  After her banishment to the Nine Hell, she had to become more cleaver with her direct impact on the material plane, and it involves you.

Tiamat’s Blessing

Starting at 1st level, when you suffer damage, as a reaction you may roll a D8 gaining the effects of the number rolled below. You may choose to roll on this table a number of times equal to your proficiency bonus per long rest.

 

1	No effect
2	Tiamat infuses her chosen one with the effects of Dragon’s Breath  lasting 1 minute without concentration. Roll a D6 for the element. 1 - Fire  2 - Poison 3 - Lighting 4 - Acid 5 - Cold 6 - Thunder
3	Tiamat’s red dragon head blesses her chosen one with fury, granting them advantage on all strength checks/saves and an extra 2D6 fire on all melee attacks for 1 minute. After her chosen one suffers 1 level of exhaustion.
4	Tiamat’s white dragon head blesses her chosen one with fortitude, granting them advantage on all constitution saving throws and a +3 AC as frost builds around them for 1 minute. During this minute her chosen one has -20ft speed.
5	Tiamat’s blue dragon head blesses her chosen one with haste, granting them the effects of Haste lasting 1 minute without concentration. The negative effects of the spell still take effect.
6	Tiamat’s black dragon head blesses her chosen one with acridity, granting them an a 10ft aura where any creature inside (if it can be) falls under the poisoned condition.
7	Tiamat’s green dragon head blesses her chosen one with effluvium, granting them the effect of Gaseous Form lasting 1 hour without concentration.
8	Tiamat blesses her champion with an astral projection of herself. All creatures within 30ft must make Wisdom save (DC 20) or become frightened of her champion for 1 minute.

Draconic Greed

Starting at 6th level, your influence towards chaotic dragon habit grows. Wealth when within your hands becomes magical.

You may for any spell requiring an item (that is consumed by the spell) instead substitute the item for straight gold at double the cost (which is consumed instead).  

You may also substitute any none consumed material components with money. 

For flavor, see the warlock upcasting spells as you using more expensive piles of money as focuses/material 

 

Draconic Resilience

Starting at 10th level, you can choose one damage type when you finish a short or long rest. You gain resistance to that damage type until you choose a different one with this feature. Damage from magical weapons or silver weapons ignores this resistance.

Dreadful Intervention

Beginning at 14th level, you can call on Tiamat to intervene on your behalf when your need is great.

Imploring her aid requires you to use your action. Describe the assistance you seek, and roll percentile dice. If you roll a number equal to or lower than your warlock level, Tiamat intervenes. The DM chooses the nature of the intervention; the effect of any warlock spell or draconic blessing would be appropriate.

If Tiamat intervenes, you can’t use this feature again for 7 days. Otherwise, you can use it again after you finish a long rest.

At 20th level, your call for intervention succeeds automatically, no roll required.
