Thanks for the answer, here is a followup question.
Are negative traits worth it if the extra xp bonus causes you to start losing xp faster. From reading the forums I have a strong impression that this is certainly the case in a4+ but is this a factor in the original trilogy too?
I have been thinking of a four person party. Which one of these would be better from effectiveness standpoint:
Human Fighter (Elite Warrior,Fast on Feet) -50% xp
Slith Fighter (Elite Warrior) -50% xp
Human Mage (Natural Mage,Good Education) -40% xp
Nephil Priest (Natural Mage,Nimble fingers) -50% xp
OR
Human Fighter (Elite Warrior,Sickness Prone) -10% xp
Slith Fighter (Elite Warrior,Sickness Prone) -30% xp
Human Mage (Natural Mage,Brittle Bones) +5% xp
Nephil Priest (Natural Mage,Brittle Bones) -5% xp
What would be the level difference at the end? Significant enough to be worth the negatives or should I just load up on positive traits instead. I have been trying to read old posts but I got rather confused so if you or anyone could clarify the matter I would be happy.
Thanks
