Well bugger.  I can't believe I failed the "forum search" test.  >.>
Also I'm a bit upset that it doesn't work underwater, as the description doesn't give even the slightest implication that it doesn't.....  And I marched into combat emboldened by a placebo effect.  
 
But that other thread makes absolutely no mention about MR effects.  Is it resistible at all?  The description also implied there is no resistance check - but somehow I now don't find that conclusive!
