Just like the title says how does xp from quests work. I had 2 party members me and the wizard in the first town i turned in a quest and gained 800xp. Out of 800 xp each character only received 100 xp each and the 600 xp went somewhere else into a black hole. Is there something i'm missing why is the xp not divided equally to your party members so 400 each?
