Not sure if this is intended or not but...
I'm questing in Stonefalls as level 10 atm.
I've just slain Alexandra Conele and secured the coral Heart, in Vivec's Antlers.
The quest gave me about 1100 xp or so.
There was another quest in that area, where I had to pray to 9 corpses to send them onwards to the afterlife, or whatever...
When I turned that in, it gave me less than 80 xp...
I noticed the same yesterday, when I had just turned level 10, and did 2 quests just south of the "Sulfur Pools Wayshrine", where you have to disguise yourself as an goblin, and then kill a goblin chieftain and free his prisoner.
Theres a 2nd quest there, where you need to pick 10 bottles of wine, or something in that line.
When I turned in theese 2 quests, it it barely moved the XP bar... I did not see the exact numbers sadly.
Just that, I was sitting on 99% full XP bar at level 9, then I hit level 10 by exploring an area.
I completed the 2 quests, and the XP bar moved maybe 1-2%.
Is this intended?
