Fishing is a highly sought-after skill that could bring you lots of money. Fishing is one of the skills that require a lot of patience. Like with Woodcutting you require an upper lvl in order to make lots of money (40plus). Lobster and swordfish are among the most profitable items in Fishing. At lvl 76, players are able to capture sharks. Sharks cost approximately 1.1k per shark, which is a staggering 30.8k per inventory. It is simple to catch sharks, all you require is a harpoon, and Catherby characters. Fishing can bring you a lot of profit if done correctly. Notice that Manta Rays are excluded from my list due to the fact that they can be difficult to catch and can only be found as a minigame.
An interesting, but completely unprofitable ability that is completely unprofitable. Smithing is the process of transform bars into objects. It's best to sell the bars than forge anything with them. For instance If you plan to make rune plates, you'll need five rune bars, each of which will cost about 17k. You will spend 85k on the platebody when you multiply 17x5 = 85. The bad news is that a Rune Platebody could cost about 60k. That means you've lost about 25k. If you don't are looking to make a loss, don't make a forge.
