Draconic Sorcery (Tiamat)

The power of dragons flows through your veins, but not from a single draconic heritage. Instead, you are chosen by Tiamat herself, the Chromatic Dragon Queen, to wield the elemental powers of all five chromatic dragon heads. This connection imbues you with unmatched destructive might and mastery over the elements of fire, lightning, acid, poison, and cold. As her champion, you are a living embodiment of her will, striking fear and awe into all who stand before you.

Level 3: Draconic Resilience

The magic in your body manifests physical traits of your draconic gift. Your Hit Point maximum increases by 3, and it increases by 1 whenever you gain another Sorcerer level.

Parts of you are also covered by dragon-like scales. While you aren’t wearing armor, your base Armor Class equals 10 plus your Dexterity and Charisma modifiers.

Level 3: Draconic Spells

When you reach a Sorcerer level specified in the Draconic Spells table, you thereafter always have the listed spells prepared.

Draconic Spells

Sorcerer Level	Spells
3	Alter Self, Chromatic Orb, Command, Dragon’s Breath
5	Fear, Fly
7	Arcane Eye, Charm Monster
9	Legend Lore, Summon Dragon

Level 6: Tiamat's Embrace

Your bond with Tiamat strengthens, which grants you mastery over the five chromatic elements: fire, lightning, acid, poison, and cold.

You gain the following benefits:

• Elemental Affinity: When you cast a spell that deals fire, lightning, acid, poison, or cold damage, you can add your Charisma modifier to one of the damage rolls.
• Elemental Conversion: When you cast a spell that deals damage, you can change its damage type to fire, lightning, acid, poison, or cold.

In addition, when you cast a spell that deals damage of one of these below types, you can empower the spell by using Spell Level +1 Sorcery points. A creature affected by the spell must make a CON saving throw against your spell save DC or be afflicted with one of the following effects:

• Fire: The target takes additional fire damage equal to your Sorcerer Level at the start of its next turn.
• Lightning: The target cannot take reactions until the end of its next turn.
• Acid: The target’s AC is reduced by 2 until the end of its next turn.
• Poison: The target is poisoned until the end of its next turn.
• Cold: The target’s speed is reduced to 0 until the end of its next turn.

You can use this feature a number of times equal to your proficiency bonus per long rest.

Level 14: Chromatic Fury

You unleash the combined fury of Tiamat’s five heads. As a bonus action, you can activate Chromatic Fury for 1 minute. 

Once you use this feature, you can’t do so again until you finish a long rest or expend 5 sorcery points to use it again.

Activate this effect by clicking on this feature and selecting one of the desired immunity. Deselect it to stop this effect.

Activate Chromatic Fury

For 1 minute, you gain the following benefits:

• When you cast a spell that deals any chromatic damage, you can add your Charisma modifier to each damage rolls.
• You gain immunity to one chromatic damage type (fire, lightning, acid, poison, or cold) of your choice for the duration.
• Creatures within 10 feet of you have disadvantage on saving throws against spells that deal chromatic damage.
• Once during this 1 minute, you can use 3 sorcery points (no action required) to completely ignore resistance for the chromatic damage dealt. For creatures that have immunity, they take damage as if resistant.

Level 18: Dragon Companion

You can cast Summon Dragon without a Material component. You can also cast it once without a spell slot, and you regain the ability to cast it in this way when you finish a Long Rest.

Whenever you start casting the spell, you can modify it so that it doesn’t require Concentration. If you do so, the spell’s duration becomes 1 minute for that casting.
