If you do this right the game doesn't screw up. He has Shock and all the equipment he had in Thamassa, which includes an Offering. You can use Google to get the codes I'm sure, or I'll look for them when I feel like it. If you change members he will be gone, but if you use the codes to get him back he'll still have any level ups you got for him.
