Other races can share their buff with me, but I can’t give mine to anyone. I know how it’s done, I did the little quest to learn about it. I told a human priest how to do it, we both had our race’s buff, both targeted each other, both did /kneel then /pray. His shared to me but I couldn’t give him mine. Char: Ashanya on Living Flame. It’s failed three times for me now.
Think I figured it out myself, maybe it’s just not a bug. Can’t be /kneeling myself when doing /pray
But- I’ve managed to teach like 7 human priests how to give me theirs by doing /kneel then /pray and it works from them 
so idk
