Currency exchange rate when buying currency on Control Panel is different, but when transferring Control Panel balance in the game (in-game currency is Family Coin), there is different exchange rate for this:
E-Global Control Panel currency is Family Coins
FC exchange rate:
1 EURO = 75 RUB = 10 Family Coins on Control Panel => equal 10 Family Coins inside the game
L2DEX Control Panel currency is TOD
TOD exchange rate:
1 EURO = 75 RUB = 33 TOD on the Control Panel => equal 10 Family Coins inside the game
Why 33 TOD on Control Panel balance are equal 10 Family Coins inside the game?
The current rate of transfering for Interlude-Final x7: 10 FC = 33 ToDs. If you put 20 ToDs for transfering, then you get 20 Family Coins in game and you will lose 66 ToDs from your MA account.
So, at the end the cost of all items on Interlude Final x7 is the same for both L2Dex and E-Global projects.
