Erase

You sit in a meditative position in a casted chalk circle for an event or curled in the fetal position in a cast chalk circle for a person. You stay in this position for 8 hours chanting the incantation.... Res vim extermina (for an event) or  Vim extermina hominem ( for a person).

This spell has the ability to permanently erase the memory of a person or an event or both from memory of the target. Up to two (2) targets can be affected. If others try to mention the person or event they are unable to do so and will forget to persist with questioning the affected individuals and will temporarily be affected by the spell themselves as long as they are in contact with the targets of the spell.

This spell is permanent until it is dispelled or until the death of the caster. After spells casted the caster receives one (1) point of exhaustion for every event or person erased from memory. This spell then cannot be cast it again for one month.
