Mana Blood (3.5e Trait)
From D&D Wiki
[Magic / Race Trait]
You were born with mana flowing through your body. You can cast your spells using your blood but with a potential toll on your body. You may sacrifice hit points to cast spells. For each level of the spell you must spend 1 hp. However, if your damage take from this trait exceeds half your hit points you become fatigued. If this damage exceeds three quarters you are exhausted instead.
Prerequisite: Character creation
Benefit: Allows the caster to be able to cast spells using their hit points instead of their slots.
Drawback: When you do sacrifice your hit points to cast spell, it could leave your body weakened if over used.
Normal: You cant use your blood for spells.
