Soul Arts/Shadow Arts
Amemait Deletrius Tout- erases the target from the universe, even in the afterlife they still cannot live
Anata Naru- an unavoidable curse; causes the target and the caster to switch bodies (unavoidable meaning that it passes threw all shields). When cast by an extremely powerful person the curse can remove the targets soul from their body (like a dementors kiss)
Itamuda- Creates a Dementor
Linux- Gives a Dementor eyes, makes them immune to Patronus charm
Wraithus- turns the caster into smoke; makes all spells pass through him and allows the caster to travel threw walls etc. However when the caster is smoke he cannot cast any spells of his own
