I heard there is a reflexive gift that allows one to pay variable gnosis to add a +2 difficulty per gnosis spent to attacks aimed at the targets mind. Does anyone know of a gift that is like this?
A gift that raises the difficulty for attacks against the minds does instantly ring the bell of Shell (Metis Rank 3) from the W20 prints to me, but it is a full immunization, is a new one and so it clearly isn't this one. It does allow us to gauge that the gift we are looking for is most likely a rank 2 to 4 gift! So let's sift and see what we find...
Mindblock, a Silverfang/Stargazer Rank 4 gift, is very similar to Shell and I could trace it back to the revised edition core book, I can't find my 2nd edition core book at the moment.
"Any direct mental attacks or attempts to control the Garou's mind, as well as more insidious psychic assaults (mind-reading, mentally implanting illusions or possession) are raised to 10. The effects of this Gift are permanent, but they do not apply to powers that sway emotion."
But I believe it is Resist Temptation, Stargazer Rank 2, Tribebook Stargazers p.51 (which is 2nd Edition):
The player rolls Wits + Rituals and spends one Gnosis point. Each success raises others' difficulties to ensorcel or supernaturally coerce the character by one. For instance, a vampire trying to Dominate the Garou would find it harder to succeed. Against non-supernatural coercion, this Gift is automatically successful. Thus, mundane con artists and temptresses have no power over the Stargazer.
