School of Hemomancy

The School of Hemomancy is built around the control of blood and only very few beings are skilled enough to take up this school of arcana, and only a select few of those are capable of using the magic. Hemomancers are able to modify certain spells they hold in their spell books using their own life force to do so.  This being so makes the Hemomancy school a quite unpopular one, due to them being controlling of their own life force and others to spell cast, being an offset of Necromancy they typically are seen in the same light. That being they dont typically work well together, with the difference of control of undeath or control of life, causing bouts between the two classes rather frequent.

Bloody Savant

Beginning when you select this school at 2nd level, You can select a number of spells to be considered Bloodied. These spells you always have memorized, meaning you don't need your spell book to write them into/on to a scroll or spell book. When you cast a bloodied spell you can deal one of your hit die + your Constitution modifier to yourself (this damage cannot be resisted), doing so you can and to the bloodied spell the same hit die + double your Intelligence Modifier additional damage to the spell. If the Spell doesn't do damage you can extend the duration of the spell by the roll of your hit die times the original duration of the spell. If the spell has a duration longer than 1 action/bonus action(such as flaming sphere), this effect targets the duration over the additional damage.

The Number of bloody spells you can choose equal to your Wizard level. Each of these spells must be of 1st level or higher and must be a spell you can already cast.

You also gain the [Spell}Spare the Dying[/spell] cantrip

If the spell dispel magic is casted on you, while this ability is active then you must roll an intelligence save against the caster's spell save dc, on failure this affect ends. If the dispel magic is equal to 1/2 your wizard level or greater it automatically stops this ability.
