New Mob: Seer

This new mob, the Seer, would stand at a player's height and be rarely found in the End islands. The Seer's namesake derives from its behavior: it tends to closely watch any passing players. Naturally neutral, the Seer wouldn't attack the player until it came within a close distance. The appearance of this mob is what makes it stand out, because it looks like the player! This unique characteristic might attract players too it, which would trigger its hostility.When killed, it would drop something like a Potion of Mirroring.
