Well I worked it out and I'm definitely not doing
![Razz :P](https://s.rsbandb.com/img/forums/smilies/icon_razz.gif)
seeing as dragon bones are the only bones anyone would ever be wise enough to use to get to 99 prayer (you don't see zezima or duffy using big bones/bones for 99 prayer lol) it would mean this (for me):
-Level 53 - 99 Prayer
-12,892,143 XP to go
-179,058 dragon bones needed (2,353 per bone brings total cost to: 421,323,474gp)
My question is: Why don't people use ourg bones? 140 experience, double dragon bones, I would only need 92,087 of them. But then...I saw why, 14,400gp PER BONE, crazy stuff! That would cost 1,326,052,800 (almost 1 BILLION more!). I am still, however, confused, go to the GE database on the runescape website, and there are two 'Ourg Bones' (
