To anyone who can answer, is there really a benefit to upgrading Acolyte of Kelemvor to epic? Don't want it to be a waste. She's currently rare maxed, thanks.
As far as Neverwinter wiki can say, the companion has +5% incoming healing bonus on epic, 3% on rare. So it seems to scale similarly to any other companion.
