Scared Clay is very good if you use it in the right manner. I just got it and it is they same bonus as rune armour but it gives double xp. Here is an example on how to use scared clay in the right manner:when you are going to get slayer or any combat level up such as attack, defence, strength, ranging, or magic get it up but while you are also getting your slayer level up so you are getting double xp in two levels. I hope this has helped you.
comment rate and tell me anything you would like me to make a video on or post and I will hopefully do it.
