I do not spend money on maplestory2 MS and am considered underfunded, but get around it. I have friends that give me their"bad scrolled" items that are better than mine, even if they screwed their scrolling up it. There are some really wonderful MaplestoryM Mesos players out there which will assist you also. In terms of getting mesos, you may sell boss drops and such. I have a tendency to NPC most stuff because of hating the free market. Just look for a few people around and talk to them.
You would be suprised that they might assist you..or even invite you to their guild. Then someone from my guild essentially gave me awful"CRA" equips. Now all I want are the pants and I got the whole set. Meanwhile, I am fighting GOLLUX also due to his rings and such. I'm also doing Commerci boat quests to your sweetwater items. You might consider trying for these too.
There was also a poster that made a list awhile back on how to get some good equips. I printed it out and ill try to summerize on here what he posted:Fight Easy mode magus. He drops nova equips, which are considered 2nd best equips in game.Do Crimsonwood questline to open bosses Gollux and Commerci up. He drops decent face accessory/eye accessory.
Fight normal horntail. He drops a wonderful ring.Monster park tends to get alot of drops inside. Try playing in there for a set of items you can either sell buy Maplestory mobile mesos or use yourself.level 150 ghost boat has greatest badge in game, so do this questline.Get alot of reward points to use cubes, hammers, and stuff to upgrade equips.take benefit of events. They occasionally have great items.Don't be reluctant to upgrade current equips if you believe you going to have them long time.
