There is actually no rates... but it wouldn't let me enter 0. There is no need for them.
-No Grind
All of your equipment is available from a convenient NPC.
-Balance
I tend to try to make it as much like kRO as possible without the grind.
-No Risk
You can equip in minutes, so even if you hate the server, you have no investment to lose by quitting.
-Consumables are sold at iRO market zeny rates.
-There aren't really any EDP noobs here. It takes a while to earn enough zeny to buy them.
