Valhriir Auvrghm:
Could you please tell me what levels the 20,000 XP makes Valhriir?
Valhriir, as a warrior/mage/thief, you'd split it three ways 6,666.67 to each class. Since your DEX and INT are above 16, I assume you get 10% bonus for the thief and mage classes. So, by my reckoning and not counting any other experience awards you may have received previously:
Warrior - 6666.67 experience points - 3rd level
Wizard - 7333.33 experience points - 3rd level
Thief - 7333.33 experience points - 4th level
