Goblin crusader casts Power word stun. My character got a 4 willsave. Also he wearing Mask of Mental armor. Which gives +4 to saving thros against mind affecting spells. (Power Word Stun is one of them) My character rolls 1 (+4) against dc of 19. he fails and stunned. But... There should Be 1+8. Cause his natural saving throw is 4. And 4 must come from Mask of Mental Armor, cause its gives bonus +4 against mind affecting spells. Mask isnt working?
Another bug about this situation:
BGTSCC wiki (and any other resource bout NWN2) says about this spell
This spell automatically stuns a single target for a duration based on the target's hit points:
Under 50 Hit Points: 4d4 rounds
51-100 Hit Points: 2d4 rounds
101-150 Hit Points: 1d4 rounds
151 Hit Points and above: No effect
My character had much more than 151 hit points. But still have been stunned, while there should be no any effect.
P\S i have screenshot with details and proofs. But forum says i'm not allowed to attach files or post urls
