First off, this might not be the best way or your way of doing it, but this is how I did it multiple times fairly easy and without risking way too much money incase i do die.
Step One= Gear up and bring what you need
Step Two= Teleport to the Minigame, click this icon and then click tzhaar.
Step Three= Go into the cave and get ready for a 5 boss fight.
Bosses in order and the protection prayer that I use
these are the prayers I use, you might wanna try something else, up to you, this is just what I use. Note tho, you might need to eat on some of the bosses due to multiple styles of attacks. If i'm wrong, please comment and I will change and correct.
Step Four= Equip that shit!! Congrats on getting your kiln cape!!
