When i got lvl 19 i was with 420g in my inventory, after that i bought my yak for 250g and im making almost 120g per day.
Its a bunch of lies when this guys says go and hit lvl 30, ill give u some tips right now:
1.- Kaslow plaind (i say kaslow plains cuz i made it there but yeah u can do it in every map except newbies) get a good spot near "trees" and kill the littles bottles and boxes, u will got Jelly Rabbit Coin. When i was lvl 12 i got a coin and i checked for what is it, i found the npc and i notices i need 3 to get a box and i said to myself "oh man i need 3, this is ****, i better check how much can i sell this" so i notices in very store a JRC is only 75s but just for curious i went to AH (auction house) and... OMG 1G???? and yeah i sold the coin for 1G in no more than 5 minutes, so i just say to myself again "ok dude, lets make money" actually im making almost 120g per day, selling around 90 - 100 JRC.
Ok, im talking to u who r sating right now "this is bored" and yeah this is bored maybe but is the better way when: ur doing homework, ur watching anime, u have ur syster yelling near u and etc... its easy, fast and symple.
Right now im a high lvl with good items and blah blah but somedays when i get really tired to do Dungeons Runs or train 25 hours, i took a free/relax day and i sit in everymap hitting bottles and getting JRC.
2.- The other day i just heard a guy from my guild: "YAY! ME IS RLZ" i was like "wtf¿?¿?¿? o.O" and i asked wut happen so he told me "man at least i have my first 100g, so i said "OH thats nice" ... 2 seconds after that i press G and.. OMG THIS GUY IS LVL 14!!!
Secret: craft / salvage
actually, well not actually but going back in that days a "Mysterious essence costs almost 1.4g" this guy have 3 sprites crafting greens and oranges alllll the day, of course he spend money in sodas and "cookies" (sorry i dont remember the name to that items to raise stamine cuz i call it cookie) some oranges, as everybody knows, can have u 2 mysterious essence and with luck u can have an event and the sprite will give u 1 more, so there is 3 mysterious AND YEAH! sometimes u dont got any, but do it all the day and trust me, u will be rich that material is really needed to craft, and almost everybody likes craft set orange lvl 21.
3.- I didnt remember this about the farm who a guy told me before, but yeah i know this method too................. ****! i will edit after the server comeback if my friend is online.
