I got a Barbarian 9, Druid 6 at level 15.
Barb 9 gives 3 Rages. I went up the NP Bear Rage tree all the way. Two of these enhancements say they give two Rages each, so that's 4 more. Actually the first one says two charges which is inconsistent language but I'm nitpicking here.
Yet I'm at 5 total Rages instead of 7. What am I missing here, or am I being robbed of two rages aka bugged?
