Overflowing Force (Mythic).
Whenever you deal damage with a spell or weapon attack, you roll twice the normal number of damage dice. This applies to all effects that involve damage dice, including cantrips, smites, sneak attack, and magic weapons.
Example: A Fireball that would normally deal 8d6 now deals 16d6.

Constitutional Powerhouse.
You add your Constitution modifier to every instance of damage you deal with a spell or weapon attack. This stacks with any other modifiers (e.g., Charisma or Strength).

Life Is a Weapon (Mythic).
Whenever you deal damage with a spell or weapon attack, the target takes additional damage equal to your maximum hit points.

• This bonus damage is of the same type as the original damage.

• It ignores resistance and immunity.

Devouring Impact.
When you reduce a creature to 0 HP with a spell or weapon attack, you gain temporary hit points equal to twice your Constitution score.
