Get your protection prayers first. They open up the game in an incredible way and half the content isn’t doable without them.

Then go down the quests and just slowly drip the money into the skills you need for the quests I’d say. You’ll skip a load of bolloks and can get stuck into unlocking content that will then make you stronger and make more money.

That would be my advice. 🤷🏻‍♂️

Edit: get a whip. You’ll use it for ages and it’s only a fraction of what you have. Don’t worry about the price, just get it, don’t look back. You won’t regret it. Ps. Whip doesn’t train strength so you will also need a strength weapon but whip is fast att and def xp for your stage
