I read a post once that the max out level is 50 for all NPC's and so I decided that I would switch character professions once they had maxed out spells (about levels 22-25). So far it is working great. My former Samurai is now a Ranger and working on skills he never had before. My former Ninja was a Psionic until about level 9 (in order to get to level 5 spells) and is now a Monk(which compliments several great skills she had as a Ninja). My Valkerie is now a Ninja Lvl 9 and working her way through those skills. My former priest is a Lord since he finished his spells at Lvl20 or so. All are around Lvl 35 total. However those who wish to do this too Note: You need MEGA experience points after about Lvl 25. The easiest way to do this is in the Mountain wilderness where Molten Scorchers offer nearly 1 meg per kill. You also have to make the rounds of the other areas via Portal spells often. You can increase your Alchemy skills by making potions and by selling the good ones eg Renewal back at shops. It gets a bit routine with the hack and slash but it is a way to give your characters 2 or more worthwhile professions
