The existence leach spell can only be used by Draconic mages. The spell summons leaches and they leach away one spell from a creature forever and if the spell caster gets a DC 24 str roll then they can leach 2 spells. If the target doesn’t have spells, the target takes an extra 5d12 piercing damage and the leach stays and starts taking away the targets blood until they get a remove curse spell. This spell also takes away 1d4 health per level 1 an extra 1d4. This spell will also give the creature the spell is cast on the prone effect. To use this spell, you need to sacrifice a drop of blood from yourself and take 2d4 piercing damage. The target must succeed a DC 30 str check and they only loose one spell.
