Paladin Solo Guide that I took!

[Heartsbane]

At 20 I think I stayed on prince side. Prince is 18 and highest on that side. You can kill the named on prince side and the occasional protector may still be blue.

So I go in first door on prince side and follow circular path through jail killing
Trainer
Training Kobolds
Kobold Pit Fighters
Jailer
Occasional shaman

Than I kill food master and smithy

Head down to prince kill him and any
Large Kobolds
Elite Kobolds
Shaman’s
Huge Kobolds

Do that until 24-25 and then head to king side
