Here's the situation: I have a character with spell save of 45 and mental save of 40. Nothing to write home about, but still decent. However, he got hit a number of times by forest wights casting Mind Disruption and getting cross-tiered Brainlocked (!), while these wights have only spell and mental power of 43 and 24 respectively.
I thought they would have a hard time getting the spells through to me, let alone getting a cross-tiered effect.
