Great job!
Immortality may be fitting for the nazguls as well, maybe unless they are killed in a certain way they keep coming back?
it's really cool
if there is going to be the hero"ine" Eowyn, i think she should be the only one who can get rid of them
NO. the only reason she can kill him is merry's stab in the back: the blade he has was made to destroythe spells holding the nazgul together. when they were gone, he could be killed like any man.

By their logic of existence - being bound to the ring- probably even after the witchking was killed by Eowyn he should have probably retaken shape after some centuries if the ring hadn't been destroyed by then.
I think immortality is quite fitting but maybe they should need a couple of turns to respawn or even require more and more turns the more often they die but only until the rings get's destroyed.
Speaking of Imladris where Elronds spell has washed them away? In this case they were not killed but just their mounts and armour/clothes we're severed from them. As far as read(if we can trust roleplaying material that is) they need physical objects to maintain shape in the real world and mounts(this is from Tolkien himself) to provide them with eyes to see. After Imladris they stumbled blindly and shapeless(but not dead at all) back to where their master is.They will raise again at the dark tower of mordor. If the front is far away from mordor they will need more time to get back to action.
