Tuska Comes

The currently untitled World Event 3, first mentioned at RuneFest 2013 and expanded on at RuneFest 2014, is an upcoming world event involving four factions (Saradomin, Zamorak, Armadyl, and The Godless) banding together to try and kill the blind boar god Tuska, who is hurtling towards Gielinor in an attempt to devour it. Although players will be unable to side with Tuska, they will be able to side with one of the four factions trying to kill her. Its original release date was the third week of May, but was moved back to 1 June 2015.

On 24 May at around 19:00 game time, this was teased in an unannounced phenomenon where the screen shook and people collapsed. A translucent image of Tuska's face was shown along with the message:

Deaths in the event are safe, and Ironman accounts will be able to participate in all content and have access to all rewards.

The event
Players will be teleported from Gielinor to Tuska and the islands surrounding her by astromancers. A representative from each faction (Scopulus for The Godless, Kamiee for Armadyl, Bree for Saradomin, and Moia for Zamorak) will be at the lodestone at the base of Tuska's spine for players to sign up with.

Each day will be treated as a new round, where the faction that deals the most damage to Tuska wins the day. Players must make their way from island to island to reach the front of Tuska, where they must stab her weak point with a Tuska spear, god-aligned to the faction the player chooses. The islands in Tuska's orbit, remains of planets that she has devoured, contain remnants of Anima Mundi used to charge the spear. On certain islands, players can kill lightning sprites to obtain energy and deposit it into lightning collectors, a mechanic similar to Divination. Other monsters include "lightning beetles", modeled after Kalphite Workers, and a stronger form of Airut.

Tuska can be also engaged through non-combat skills, including Construction, Dungeoneering, Divination, Farming, Hunter, Prayer, and Woodcutting. Skilling nodes will be located on Tuska and the surrounding islands, such as quills on her back which can be cut down for Woodcutting experience, and leftover stumps which can be balanced on for Agility experience.

Tuska will adapt to players' actions as the event progresses. Contributions from each god faction will be tracked; at the end of the event, the winner will be determined by the side (Tuska or Gielinor) that has won the most "days". An unrevealed third outcome is also a possibility.

Rewards
Performing activities will give a currency specific to this world event, as well as renown stored in faction-aligned tokens. Rewards will include tiered emotes, cosmetic overrides of the god-aligned spears, a new ability, and World Eater armour, a type of warpriest armour which will increase players' chances of landing critical hits based on the number of pieces worn.

Rewards from the two previous world events, such as warpriest armour and abilities, will also be available for purchase in the reward shop; the cosmetic rewards from previous World Events will not be available.
