Best & Cheapest Way For Prayer

What's the best and most cheapest way for me to raise my prayer from 34-60
I heard sumtin like bone meals were good but explain please =/.

Pest control .. it takes all day to get 2 lvls though lol

theres a quest which you grind one bone into a vial and when burried in sertant place gives 4X as much xp

But pc might be a good way :\

Or bone yard (very slow)

Ill just spend erm, 2.5M on dragon bones and do the extofunkas thing Lol
Get me to 60 prayer, One problem though, I need 2.5m first...=/

Well if your a FREE Member, Kill Giants and Moss Giants and get Big Bones or just buy them :), and for Paying Members, I don't know then.

Using the bone meal, Can i pray at someones guilded altar at their house or sumat and get more xp? =/ Also, how much more does it give?

thats esco thing takes forever i bought 1k d bones took me 4 hours just to do 300

I have forever, well, 1 week max

cuz what u got to do is grind the bones put in a pot then u got to take buckets go downstairs 4 lvls to go down then get that acid thing then u got to go all the way upstairs and use both bones and acid.meaning u can do 14 at a time maximum

Shuld I just buy 1k d bones for 2.5m (If i ever get k) and use at someones gilded altar and get 350% xp for each bone. But how do I use a gilded altar. Rofl im sucha prayer nub.
