How to Become a Prayer in runescape.

Prayer is a skill that allows players to use prayer(s) to generate advantages in combat. The ability to do so is achieved through evoking the power of certain gods of RuneScape. All players start with limited access to the Prayer skill. As one's Prayer level increases, they gain access to new prayers. As players traverse the land and complete many adventures, they find themselves presented with the opportunity to gain the prayers and blessings of various gods such as Zaros, who is related to RuneScape's deep past, and Saradomin, the god of order. Some of the strongest prayers are only available after doing certain member quests. Prayer is difficult to train in Free-to-play, because the most amount of experience granted in Free-to-Play comes from big bones, which give only 15 experience.
Prayer, unlike most skills that are directly related to their name, cannot be trained just through the act of "praying." In fact, Prayer almost completely relies on the act of burying bones to gain experience. Prayer is currently the slowest skill (according to player polls) to raise as a free player. However, its benefits in combat can be exceedingly useful, especially amongst members. Through various members' benefits, Prayer can become much faster and easier to raise on member servers. The current minimum requirement to be ranked (at rank 2,000,000) on the hiscores for Prayer is level 43. As of 09 January 2011, there are 22,300 players that have achieved level 99 in Prayer.
