Does anyone have some quick ways to gain experience points? Please help!

First, set Respawn to Frequent and "Hard". This gives you more XP per encounter, and more encounters.

Fight Rumphy in the Crypt. He respawns everytime you load the Crypt, and he's worth good XP (1167 for starting characters in a 6-character party, easy to level up to level 9 or so w/o a problem).

Other ways:

Do the Jathil quest in the Ishad N'ha Priest Guild (unlimited XP; 750 points everytime you enter the guild)

Do the Leprechaun quest for the Thieves' Guild in Brimloch Roon (unlimited XP; 5000 points everytime you enter the guild)

Out past Brimloch Roon, just about everything is worth 1000+ XP.

If you have a Paladin, get to Priest's Guild level 5 and get him/her the Crusade trait: double XP for fighting undead. You can mop up in Shurugeon Castle and Skull Island.

There's an unlimited XP opportunity in the Shrine of Anephas in the Scorpion pit: press the buttons to fill the pit up with scorpions, then firestorm them (or other storm spell). Repeat.

Hope this helps!

Thank you once again, wise sage.
