Hello, already do not make the mistake of buying special set, bow punch, apple cheat or other, keep your money. The best is to buy immo set and s5, MP me in game "Bobdu46" I can offer free. The best way to make money is of course to do the fishing events x2, so look well /event the hours, even if unfortunately a lot of not work because buged. So my best advice to make money with money is to enchant. Get some S5, buy/shop some unenchanted swords and bows OR go get them in pvp, combine two items in the crafting in the inventory. You will start enchanting at a low level, so don't use exp without "knowing the enchantment" that you will choose. Stay within the 5-15 lvl exp max. To change enchantments, enchant a lvl 1 sword, so all table enchantments change. Try to get enchantments like: Knockback I, Fire Aspect I and for the bow punch I, umbreaking II. Then combine 2 knockback I and you can easily sell this sword for 3k or even more. A Sharpness 5 Fire aspect 1 can be worth up to 5k, all depends on supply and demand. Talking about level 30, it's simple, level 30 is reserved only for Infinity, so if you don't see infinity in the 30 table, stay in the 5-15 exp. If you infinity, you can make 30, made to this level of exp, you can try to enchant rod max, and depthstrider boots, be careful at this level the exp is very expensive.
Here is a brief summary of my business.
Sorry my english is not very good, thanks.
