Rigour

Rigour is a prayer that gives a player 8 bonus Ranged levels when calculating hit chance, 8 bonus Defence levels, and a 8% boost to ranged damage dealt. It requires 70 Defence and 70 Prayer, and completion of Knight Waves training ground in order to be used. It was released on 19 August 2010.

This prayer is the highest-level Ranged prayer on the standard prayerbook, and is the Ranged equivalent of Piety and Augury.

Trivia

 * On the first day of release, the Rigour prayer was not working properly and did not increase damage dealt by ranged.
 * Before the Evolution of Combat update, the Rigour prayer was unlocked by buying it from the Rewards trader, rather than completing the Knight Waves training ground. Players that bought the scroll of rigour before were refunded.
