Is this a bug or what?.. I found a luxon priest while VQing Drazach Thicket, although this is a kurzick area and currently under kurzick control. As a result, i was able to gain both blessings and gain a permanent 6 pips to my health. Perma Healing Breeze ftw?
It's a normal thing. The drawback is that when you use kurzick faction, all luxon faction you gained will be lost and vice-versa, so gaining both faction at the same time has little use.
