Purification of the arcane blood

This is spell requires many sacrifices to be completed. The blood of those sacrificed needs to be purified with an additional ritual that takes an hour to complete. However it makes sorcerers or those who use their blood for arcane magics to gain more magical power. However it is done at the cost of the caster.
This purification process allows casters to use much greater spells than they would normally would be able to cast. When purified blood is consumed the caster becomes wilder and more prone to aggression. The more blood is consument the more prominent this becomes. When the spell is cast that they set out to do there is a heavy toll on the body and the mind. When the disparity between the original casting and the spell cast is too big there is a chance of death for the caster.
The substance that is created has been given the name Siliander.
