Incredible Reflexes is a Prayer that gives a temporary 6 bonus levels to a player's Attack skill when calculating hit chance. It cannot be used in conjunction with any of the other prayers that provide an attack bonus, but can be stacked with a Strength and/or Defence prayer. It replaces Improved Reflexes when unlocked. This prayer is widely used because it greatly increases the chance of players hitting other players and monsters with a melee attack. Paired with the Ultimate Strength prayer, which grants a 6% increase to melee damage, this an extremely effective combination until Chivalry is unlocked.
