Hey everyone, Nub again. This post is for the people who have just begun. So first of all, you have to decide if your going to be a skiller, pure, or just a main. If you are going to be a skiller, you want to start off by mining, mining is a very good money method. So to mine, go to your magic spellbook and keep looking at all the teleport spells until you see a skill teleport. When you see the skill teleport click it and talk to bob, buy an iron and rune pickaxe from him, go through the portal, head west and there are the rocks to mine!
If you are going to be a pure, start off the same way until you make decent cash as in at least 10M. Once you make 10M click the monster teleport which is located in your magic spellbook, it should be the first one, and click rock crabs. you should train your combat from 1-50 here, then 50-75 at hill giants and 75-99 doing slayer.
If you plan on being a main which is all skills 105, you should start off by mining to make at least 120M, each runite ore is 100k each, if you have 85 smithing, smith them into bars and they will be runite bars which are 150k each. You should make at least 120M so you can buy some gear, food and supplies. I would recommend you train 1-20 combat skills at home. 20-50 you should go to crystal key minigame which you may need lots of food but trains easily! 50-75 killing dragons from going to your magic spellbook and clicking monster teleports, and click brimhaven dungeon. Remember to bring your anti-dragon shield!
This is my getting started and how to make money. I hope this helps
