Rage Winterchill
Rage Winterchill is the first boss you encounter in the Battle for Mount Hyjal. When you enter the pre-zone area, take the portal to the immediate left to enter the human town.
Abilities
Rage Winterchill has 4,500,000 hit points and four abilities that the raid needs to be able to handle. Two of the abilities do direct damage to random players and require the most attention from the raid.
Death and Decay: An AoE spell that lasts for 10 seconds and ranges 20 yards, which is channeled by Rage Winterchill. It does the equivalent of 15 percent of the player’s health in damage to the player ever second the player remains in the AoE.
Frost Armor: Similar to a frost mage’s frost armor, Rage Winterchill’s buff reduces movement and attack speed of players that hit him.
Frost Nova: An AoE spell cast to freeze players to the ground.
Icebolt: This spell freezes a random target for 4 seconds, doing an initial burst of frost damage, between 4,000 and 6,000 to the target and 2,500 frost damage each second for 4 seconds.
The Pull and Position
Start the event by talking to Jaina Proudmoore. After killing the eight waves of mobs, Rage Winterchill spawns and invades the camp. The pull is relatively easy, Rage Winterchill can be fought anywhere in the camp as long as you do not engage Jaina Proudmoore during that boss fight due to the possibility that his Death and Decay or Icebolt spells could target and kill her. Many guilds chose the open space that is in the center of the camp, directly between Jaina Proudmoore and the spawns’ entrance. This allows your raid to spread out along the sides. Other guilds drag him to an area that is smaller and closer to Jaina Proudmoore but again do not engage her. This keeps the raid closer together and Jaina Proudmoore gives an aura to those within 20 yards of her that increases players’ spirit by 100 percent. Use a hunter to misdirect Rage Winterchill to the

tank or have a tank pick up as soon as he enters. This depends largely on where he is going to be fought since moving him is not easy since he casts a great deal.
Battle
Waves
You have 8 waves of mobs to deal with before Rage Winterchill spawns. Each wave contains anywhere from 12 to 18 mobs. The mobs preceding Rage Winterchill are abominations, crypt fiends, ghouls, and necromancers. Their abilities are explained in the introduction to this instance. The raid has about 2 minutes to kill the wave before the next wave spawns and attacks with the exception of wave 8, which gives about 3 minute of recovery time between the wave and the boss. Ghouls are in almost each wave as are crypt fiends. Shadowy Necromancers appear around wave 4 and Abominations start to appear at wave 6.
Engage the Alliance NPCs as much as possible during the waves. They have a lot of hit points but do average damage. However, every bit helps! Use two players to pull a weak mob from each wave back to Jaina Proudmoore and one mob to the riflemen. If using hunters, have the hunters kite the mobs back to the AoE area. Players with taunt abilities should taunt mobs off NPCs to keep as many alive as possible since they can assist with boss encounters.
Rage Winterchill
Rage Winterchill is rather straightforward as far as tanking and damaging him. His abilities are what can be problematic. Raids new to this fight must learn the importance of handling Death and Decay and Icebolt abilities.
Death and Decay affects all players within the AoE target area. To effectively handle it, move! Do not wait until that last spell cast finishes or to attack the boss one more, just move out of the Death and Decay as soon as possible. Healers are going to be divided between watching the tank and Icebolt targets so the quicker you move, the more likely you are to stay alive if healers cannot immediately switch to heal you.

Icebolt targets need quick healing to keep them alive through the spell. Have healers with instant or quick cast time spells and healers with quick reaction times healing the Icebolt targets. Remind the healers not to bundle in one spot so that more of an area is covered by healing in case an Icebolt target is caught right after moving from Death and Decay. These healers need to be ready to start healing as soon as Rage Winterchill targets a player but they can help healing throughout the raid while waiting for the Icebolt to cast.
The Rage Winterchill fight is not that hard and some guilds have killed him with less than 25 players alive or attuned. Getting use to the waves and being able to quickly kill each wave mob is essential to this fight. The quicker you are, the more recovery time you have between waves or between the boss and wave 8.
