There are two Crystal Traders in the game who are interested in trading their crystals, free of charge, for those Simon currently has in his possession. The one in Aljiba will trade a Blue Crystal in exchange for a White Crystal. The one in the town of Aldra will trade a Red Crystal for a blue one.
If after having made business with a trader the player attempts to trade their crystal for a less powerful one, the trader will say that he's not interested and the transaction won't take place.
- Since Crystal Traders always trade a more valuable crystal for a less valuable one, they may be collectors or ignorant of their powers.
