Eagle Eye

The Eagle Eye Prayer gives a temporary 15% boost to a player's Ranged skill. This prayer was released on 22 August 2006. It cannot be used with any other range-modifying prayer, and requires a prayer level of 44 to activate. It is the third prayer unlocked that modifies the player's range skill.

Glitch
There is a glitch (as of 25 March, 2009) that if you click on the Eagle Eye prayer in a free world, it will give the message "You need to be on a members' world to use this Prayer" and then the prayer activates. The same applies to the prayer Mystic Might.
