Alpha Yeti

The Alpha Yeti is a boss mob added by Twilight Forest. These bosses appear like large Yeti but with six blue horns and red eyes. It has health and is represented by a white boss bar. The Alpha Yeti resides in the Yeti Lair in the Snowy Forest.

In combat, Alpha Yeti have two forms of attack. First, the Alpha Yeti will attempt to shoot Ice Bombs at the player, which will leave a freezing area that deals damage quickly and over time. The Alpha Yeti will also attempt to fling the player if they get too close. During this phase, the Alpha Yeti becomes immune to any Arrow damage, so the only choice left is to deal melee damage.

Once enough damage has been dealt to the Alpha Yeti during this phase, it will begin to wildly flail it's arms around and jump around. This will deal damage if the player is within range of the rampage. Along with this, any blocks around or above the Alpha Yeti will break, which may dislodge any Ice around it, which may deal some damage. This will continue for several seconds before it grows tired and sits down, leaving the Alpha Yeti open to any attacks for a short time.

The Alpha Yeti is protected by the Twilight Forest Progression line. In order to be able to fight the Alpha Yeti, the Ur-ghast (prior to 3.7.424) or Twilight Lich (as of 3.7.424) must be defeated. Once the Alpha Yeti is slain, the Aurora Palace is unlocked, allowing the player to proceed.
