Fastest skill

Cooking if you have the money, getting the gauntlets its easy peasy and its smooth sailing from there or thieving now lol

Did you imagine starting off with a new account? The requirements for the gauntlets are indeed not that bad, but it may take some time if you have to start from scratch. The same goes for the money. I'd say Cooking is not the most expensive skill, but making enough money to get it to 99 or even 200M xp does take some time. If you have to start making the money without any skills or money to begin with, it isn't too easy either.

Thieving does indeed seem like a fast skill too. You can start right of and you don't have many requirements before being able to get some fast xp. Since you also added the 'now' in there, I am guessing you are referring to Prifddinas though. That place does have some heavy requirements if you'd have to start from a new account.

Would you still say one of these skills is the fastest to 99 or 200M xp now?

i have no idea which one is the fastest

dg with a good team can be really fast
herblaw ofc
summoning is piss fast
idk the best rates of smithing in artisans, think it could be quite fast
cooking if doing wines (for 99 not unreal but idk if anyone would do it for 200m since cooking rocktails is so much cheaper)
crafting - cutting dragonstones
fletching - broads

I don't think you really considered that part about requirements I wrote. All of the skills you just listed are very fast, but most of them have some high requirements too.

• Dungeoneering can definitely be a fast skill, but in order to do it best, you need overall good skills. Unless you meant leeching all the way to 99 or 200M xp of course.
  
• Herblore can also be very fast, but it would take a long time to make all of that money.
  
• Same goes for Summoning, I gave some time consuming examples for that in my original post.
  
• The fastest rates for Smithing are also rather costly.
  
• Same goes for Crafting, definitely with dragonstones.
  
• Fletching requires some money to start off too. I'm not sure about the broads method though.
  

Thank you both for your responses! As you see, I'm really trying to start a discussion here. I think it may turn into an interesting one. You've already started contributing to that.
