Everlasting Bloodline (New Version)

Strain Spells

Your blood pulses with arcane power, ready to be unleashed at a moment’s notice. As an action, you can turn your very blood into raw magic, casting a spell without expending a spell slot. This comes at a cost, as your lifeblood is consumed in the process, causing you to take damage equal to a roll of your highest hit die times the level of the spell plus the number of strain spells you've used today. Alternatively, lower a concentration check DC for each 1 you lower the DC by you take damage equal to the spells level.

Reverse Strain Spells

Harness your spells to heal yourself. When casting a spell, regain hit points equal to a roll of your highest hit die times the level of the spell minus the amount of strain spell you've used today. Alternatively, increase a concentration check DC to regain hit points equal to the spell's level for ever point you increase the DC by you regain hp equal to the spells level

 

Blood Resilience

Your mastery over your bloodline’s magic has made you resilient to its effects. When you use Strain Spells, the damage you take is reduced by an amount equal to your Charisma modifier (minimum of 1)  times the level of the spell. And when you use reverse strain spells the healing is increased by an amount equal to your Charisma modifier (minimum of 1) times the level of the spell.
