or fantastical in nature, and feature different strengths and weaknesses. Players may summon a familiar to assist with combat, use special attacks called "abilities" to deal additional damage, and use potions and the Prayer skill to boost their combat prowess. Combat is subdivided into three main categories: melee, magic and ranged. Melee attacks are close range, magic attacks focus on using runestones to cast spells, and ranged attacks use projectile weapons like arrows, darts or throwing knives. These combat types make up a "Combat Triangle", which governs effectiveness of styles in a rock-paper-scissors fashion; melee beats ranged, ranged beats magic, magic beats melee, and each style is neutral to itself. The advantages and disadvantages of the combat triangle apply to both NPCs and player opponents. Players are not required to choose a character class nor are they bound to a specific category of combat. They may freely change between or combine the three styles of combat by switching weapons and armour. Combat is governed by a life points system. Every combatant has a maximum capacity of life points, and dies when their health is depleted to 0. Lost life points can be recovered by consuming certain food or drinks, or casting abilities. Players who die reappear at a respawn point of their choice with their life and skill points restored; however, they drop all but three chosen items, as well as certain common items. Dying spawns a gravestone that will hold all of the player's items and will last for an allotted time; however, there are situations in which all items will be lost upon death. If the player does not return in time, the grave will collapse and their items will disappear. In June 2012 players were invited to beta-test a new combat system named "Evolution of Combat", which included fundamental changes such as re-balancing the Combat Triangle to avoid favouring melee attacks, and replacing special weapon attacks with abilities that produce a range of effects when activated. The system was released on the live game on 20 November 2012. Various polls were also added for players to vote on in game that would determine the result of future content development, some of which would dictate the development of the improved combat system. A beta for a separate combat system dubbed "Legacy Mode" was opened to players on 16 June 2014, before being introduced to the live game on
