Blood Caster[edit]

You were once a Wizard, tamer of the arcane magic that flows through the world, equipped with your Spellbook and your arcane focus or a component pouch. However you felt... limited. Your Spellbook was so limiting and it was so infuriating for you that you chose the only thing there was to do: You abandoned your Spellbook. Now, freed of your limitation, you also freed yourself of your magical source but you found something new, you found the energy that flows through every being that can be bent for your magical purpose... and you learned to use it. You suffered a few losses regarding spells and power but your limitations are gone. Now you are out to see what your newfound powers can do.

What is a Blood Caster?[edit]

A Blood Caster is an Ex-Wizard that uses their own life essence instead of the power of a Spellbook to cast their spells. They have a mostly hidden external source that always follow them, hidden from the normal eye. Along their journey they can decide to either strengthen the ways they influence the world with their spells or increase the possibilities of their external source for spells. Whatever way one chooses bending blood to cast spells is something mostly considered unnatural and oftenly brought in connection to necromancy. Therefore it is not appreciated in many settlements and societies. However those that search for the dark secrets of death and power will likely be interested in a Blood Caster.

Creating a Blood Caster[edit]

Blood Caster, Source

First of all when creating a Blood Caster you have to keep in mind that you once were a Wizard. You either still feel bonds to other Wizards since you once practiced the same ways as them or you broke all bonds, potentially even having developed hatred towards them. Next up most Blood Casters either boast strongly about the way they found to cast magic or they keep it a secret as well as possible, not showing to anyone what they are. Lastly you mostly work for your own benefit, not being interested in the well being of others that much. However you may still find people that you hold dear, though it usually takes you a bit longer to get used to them.

At 1st level, you know three cantrips of your choice from the Wizard Spell List. You learn additional Wizard cantrips of your choice at higher levels, as shown in the Cantrips Known column of the Blood Caster table.

Blood Caster

To cast one of these Wizard spells, you must lose a certain amount of hit points descripted below in spellcasting ability or you may use a spell slot gained through another class. When you damage yourself this way, you do not make a concentration check, and you go to 1 hit point when you cast a spell that has a higher hit point cost than your hit points and the spell fails. You are unable to cast spells that heal your hit points through Blood Magic.

Spells Known of 1st Level and Higher
