Correction to the answer I don't think Renas are for the Moss Merchant; They are for the Golden Archer.
this might be considered spam but I wanna suggest u guys to add a little more info about moss, like what items can be obtained from him and if maybe the more renas u spend = higher item obtained? because moss takes all the renas in ur inventary, not just a pre-set amount ) and maybe lower the lvl requeriment xD
dude for real?? then i guess i need to read more about this server. Can you give me a link to the thread that has all that info bro? I did a search but found zit so it would be awesome if you could provide me with the link of all the information about this server's in-game automated events. we have the same problem dude, i want what you want =)
We have a GUIDEs section, all u have to do is to search... http://forum.gamesymbol.com/f10/moss-gambler-event-20753/
If that guide is true then you need to update it. You only need 10 rena, also add that you need at least 6x6 in inventory space.
True 10 Renas are needed for BlizzardMu because there were not many players maxed already but i suppose it's fine to go with 20 renas now.
