Deities and illusions in evil cities?

[sajbert]

The bog-standard advice is go agnostic but some classes can't and some players may prefer to pick a deity for flavor or RP-reasons.

Question is, which deities will actually get your bum handed to you in places like Neriak, Grobb, Oggok and Paineel? Assuming you have an illusion like dark elf, AoN or somesuch.

Particularly curious about Karana, Rodcet Nife, Erollisi Marr, Brell Serilis, Mithaniel Marr, Prexus, Tunare, and Quellious. Some of you may already have figured out why I'm asking.
