On my monk I had Chant of Resonance on, it increased my spirit regeneration +2 if I had a mantra running and extends the duration for mantras 7mins.

So, I tossed on a mantra and Chant of Resonance and got the Templar with the Inspire skill ... it did nothing. I looked at the details and it still reported 2 points of spirit regeneration. 12% of 100 would still give me 1 point of regeneration which would have been 3 spirit regeneration minimum on my details screen. Even w/o the mantra on, I still gained no spirit from the Templar.

Its the only reason I dont use the Templar at all, now.
