How can I beat the Ermor?

[Valandil]

True enough. Assassinating a wraith consul would be hard, and a dusk elder almost impossible.

How good is purgatory?
Astral is nice for solar rays/brilliance if you can get it.
The forbidden light isn't bad, but there is only one, and it's const. 8.
What about inner sun? or phoenix pyre/reinvig?

opnions?

[Cainehill]

Forbidden light is also rough because it tends to get whomever is wielding it killed, even pretenders. Big honking huge horrors show up - I've even lost pretenders to 'em.
