The Frozen Scavenger

The Frozen Scavenger would be a Pillager that would lurk in the high mountains trying to escape society. Not really fitting into the villages and not the Mansions or Outpost, they sleep in tents in the cold where they hunt around. They have 35 health points and would attack using a spear that has the natural ability to penetrate mobs. When the spear is through the Frozen Scavenger would switch to his axe to make his way to collect the spear while protecting themself. 

The Frozen Scavenger could drop Lapis Lazuli Jewlery that can be used once to temporally call snow into a biome that usually doesn't snow and make all projectiles have the ability to penetrate mobs including the enemy's increasing the difficulty and the loot.
