Snowverload

Snowverload is a members only seasonal boss released during the second week of the 2014 Christmas event. It spawns every 3 hours, in sync with the Guthixian cache and Tinsel snakes at one of these locations (different for each world):
 * North of Falador city walls
 * North of the Grand Exchange
 * South of the Clan Camp, within the vicinity of Armadyl's Tower
 * East of Draynor wheat field (stated as north of the Lumbridge crater)

Once Snowverload is found, players must team up and defeat it only using snowballs, as it is the only weapon that damages it. Snowballs may be gathered in stacks of 100 by right clicking Snowverload, and must be equipped to be functional.

The Snowverload has an array of special attacks that may hinder players during the fight, including: As Snowverload's life points decrease, he shrinks in body mass, gradually becoming smaller in size. Once Snowverload is reduced down to low health he constantly heals to 5,000 life points. At this stage, Snowverload must be lured to Santa Claus at the Lumbridge Crater to be finished off.
 * The Snowman traps you in a bauble! Roll in front of him to be smashed free. - Turns players into giant baubles, where one must run directly in front of him to be freed.
 * You've been covered with a stocking. Run around to shake it free! - This turns players into stockings, where one must run around in order to be freed.
 * You've been turned into a snowman. Find the fire entity to melt yourself! - This freezes players, and one must find the fire entity to be freed.
 * You've been turned into a fire entity. Melt the 7 snow elementals to free yourself! - This happens at the same time as other players becoming snowmen. You must run to them and melt them to be freed.
 * A present has spawned. Get in it before the snowman attacks! - Spawns a giant present, which players must hide in to avoid Snowverload's attack.

Successfully contributing to this activity will grant all participants two festive papers, the ability to deliver another present on the same day, and a turkey drumstick, roast potatoes and mulled wine. Doing the event again on the same day rewards only the food items, but not the festive papers nor another second delivery.
