Tried helping a friend transfer his accessory, and the potential went down to 0/5 and can no longer be traded… =(
I’m supposing this is needed to remove items from the game. For the same reason the durability system exists: to remove gold from the game.
This may prevent inflation in the future. The general gold and items would just accumulate as time went by. As it happaned in Ragnarok. When the server had just opened, you could easily see cards for sale for 10k
After a few months and years, you would rarely find any cards for less than 80k
