The Evolution of Combat was a complete rework of RuneScape's combat system, released on 20 November 2012. Billed as "one of the largest content updates in RuneScape's history", the evolution brings a variety of new content including powerful abilities, dual wielding weapons, new Magic and Ranged equipment and new Prayers. In addition, the combat triangle has been massively rebalanced, monsters have new attacks, and the combat level formula has been revised (the maximum combat level went from 138 to 200), although the formula was later reverted to a modified version of the original.
