From my understanding the psychic vampire is impossible to kill
without an archon, its basically the fiend with 20k hp.
Sure enough a good align conjurer sits there with his elemental and
kills it over a period of 7 tics.

But how can evils possibly kill this dude?

A lesser ice devil has arrived.
A lesser ice devil gestures at a psychic vampire, uttering blasphemies.
A psychic vampire's mental assault MASSACRES you!
A psychic vampire's mental assault MANGLES you!

yay, my devil really helping me out here :P
it was immune to all its maledictions, its also immune to my demon
leaving just the elemental :(

I think i wasted 2 pracs on clairvoyance.
I see the balancing of this spell where there is a chance
that you get attacked causing severe annoyance and chance of death.
Not, chance of being attacked with certain death!

Please dont reply with use an archon, i think that thing heals me
once every 15 rounds :P
