I would say put all your money into 94 mage first, which will be fatal for PKing aswell as quicker and also cheaper Zulrah kills.
The money needed for zulrah supplies is fairly easy to get in a day or two, mage just has to be done. Besides that work on 90+ range, that way your kills will be so much faster.
Goodluck !
Horror from the deep like people said before but you need to do a Mini-quest called Alfred Barcrawl, it's pretty easy just annoying as you have to run around the bars in different cities and get wasted on 20 gp beers.
TriBot has a Zulrah helper which tells you exactly what to do and when. It's 0% banrate and only like 12 bucks for a month, works like a charm and you will learn rotations in just a few hours.
I lost all respect for Paul in 1 second after I read this. I am sorry bro I told you he was not to be trusted hes a lowballer. Ima message you I wanna talk to you.
Collecting raw materials like blue dragon scales, White berries or even flax and craft into bowstring is decent money to start out with. Also marching is a great source for money to afk while training a main.
