The best way is to get a friend with a gilded alter and bury bones at it and you will vll fast.
If you bury bones, you will level up prayer. Increasing your prayer skill will also increase your combat level.
by killing monsters
well you just build it!
Simply pray at another altar. You will be asked if you either want to change prayer lists, or just want to recharge your prayer level. For a guide on how to increase your prayer level: http://gameolosophy.com/games/online/runescape/how-to-train-prayer-in-runescape
Ancient bones give you a lot of prayer points and they get you up levels quickly
How do I get up my prayer quick?: By going to a player owned house with a altar inside it with 2 in-scent burners lit. I advise dragon bones+ to maximize xp/hr.
If I was you go to youtube.com and type in Runescape Cooking Guide for F2P. But if you're a Runescape member you type in Runescape Cooking Guide for P2P.
Roughly about 300,000.
It depends on how high your prayer level is.
approximately 3 million gp, if you are counting from 1 lvl.
Get some bones and right click them a little menu should show up then left click "bury bones" on the little menu. then if do that lots then you will get your prayer level up. Life. But if you are high prayer and a member try buying dragon bones.
I assume you want to level up combat. Same as in the paid game - fight a lot. Your combat level is also influenced by your prayer level; but in f2p, your fastest option is burrying big bones, which is still rather slow.
