Blood Magic

Your innate magic stems from the very substance that sustains life; blood. This may have occurred due to dark, forbidden magic suffusing itself with your very being, or possibly due to a dark mark somewhere further in your ancestry. Blood magic is strictly forbidden in many civilized areas, and the blood sorcerers who use it are seen to be a bad omen for horrific events. As such, many blood sorcerers are seen to be evil, cruel ministers of magic.

Blood is Thicker

The magic bubbling within your veins has brought with it a heartier resilience for you to the world. At 1st level, your hit point maximum increases by 1, and increases by 1 again whenever you take a level in this class.

Bloody Spellcasting

Also at 1st level, you are able to disperse the blood within your body to cause more damage with your spells. Whenever you cast a sorcerer spell of 1st level or higher, you are able to expend an amount of your sorcerer hit dice up to the level of the spell slot to empower the spell. The extra damage equals the roll you make on the hit dice. If you have no more hit dice remaining, instead you roll a number of d6s up to the level of the spell slot: the number rolled is the amount of damage you take from surpassing your limit, as well as the amount of damage the creature takes also.

Crimson Restoration

Starting at 6th level, you are able to manipulate the blood of enemies you defeat to bolster your own. When you slay a creature, you may expend sorcery points up to half your level (rounded down) to draw the blood from that creature and regain hit points. Roll an amount of d6 equal to the number of sorcery points expended and regain that many hit points. Once you use this feature, you are unable to use it again until you finish a short rest.

You gain a secondary use of this feature at 14th level.

Crimson Rejuvenation

Beginning at 14th level, your capabilities of drawing the blood from slain enemies grow stronger. Whenever you use your crimson manipulation feature, you can regain an amount of Sorcerer hit dice equal to half the amount of sorcery points you expend. You cannot exceed your standard amount of hit dice in this way. You can use this feature once per long rest.

Scarlet Fury

At 18th level, your mastery over your own blood magic enables you to course magic through the veins of your enemies, causing them to rupture and harm. Whenever you empower your spells using the bloody spellcasting feature, you can opt to use the hit dice of your opponent instead to your advantage.

Expend one of your hit dice and roll. The number you roll equals the amount of hit dice of the opponent's that are used against it. Roll those dice and add the result to the damage of the spell you are casting.

You can use this feature once per short or long rest.
