Unfortunately, I found a lot wrong with this guide
I'll start with saying that when you make a guide saying you're going to help get someone a fast 99 you need to understand that some of the people are starting in that skill from level 1. Clicking on the guide I thought I was going to see something like a guide to go from 1 attack to 99. Instead you listed off you needed these certain skills before even being able to start gaining fast XP.
Another thing you should consider suggesting at the beginning of a guide is how much money they should expect to spend on gear to kill these monsters. You should also suggest wearing a Fire cape instead of a skill cape because a fire cape gives a lot better bonuses then a skill cape would.
Lastly, I would show the viewers how to get to barrows. What you did was just cut the scene then you appeared at barrows. Show everyone that you need to talk to the ghost in Falador park and he'll teleport you to canifis, the from canifis there is a teleport that you click on that will take you to barrows.
If you were to fix some of those things this guide could be very useful to others! Good idea on killing the monsters with barrows, never thought of that!
