I was wondering if using fire bolt at barrows would render me succesful at all?

 

I suppose I'd use full mystic.

 

And I also need advice on the setup.

As long as you have 43 prayer, I don't see why it wouldn't.

 

 

 

Not to mention you could use a steam staff and the latter of your chaos runes would come back from the chest.

Really? I'll try that then, thank you.

Actually, if you slayer dart you'll finish trips alot faster resulting in more cash, and more experience.

fire bolt won't be as effective as say, the dart or sallys, but it'll work.
