So there is the Rank 3 Blessing that allows the cleric to see taint, corruption etc.
This reveals mutants etc.
Now even granting that real "blessing capable" clergy are not the standard and that Rank 3 will be rarer still, I find this in need of some house ruling.
Mutants going undetected even in "high places" is a recurring theme of WFRP fluff and novels that I like. I like it as well for the wonderful reputation-ruining gossip it can create, " I hear Clothilde is unmarried at 28 because she can't afford to let a man see her unclothed.... "
Similarly Lord so-and-so being a secret Chaos Sorcerer is also a standard and I don't like such 'secrets' being outed by Rank 3 spells belonging to the official church etc.
So I want to houserule this but am not quite sure how to fix it, other than just removing the blessing from the game (Sigmar's clergy have received POD love etc. so they aren't short blessings).
I am thinking instead something that forces creatures that have corruption to make a check to avoid recoiling in Sigmar's holy light, Discipline (WP) likely to "control oneself" and avoid reacting adversely (instinctive snarl or whatever).
The GM can roll the check secretly so Players don't know "passed or there was nothing to see". A normal person who failed and rolled chaos star might "recoil from brightness" anyway and give a false reading .
What do folks think?
Currently I have no Sigmarites (and my last one was all about dealing the hurt not information magic) but in the fluff and explaining background to situations etc I like to have these things sorted.
