Observer

The Observer is a Boss found at the end of the Tutorial Troubles quest. You fight the boss after destroying the dark crystal growing out of a hill, in a zone between the crystal shard cave and the Old Hermit. it has 100 HP (+ 50 HP with the Shield), but can only be attacked after first destroying the surrounding shield with magic, then attacking it first with archery, and then with melee attacks.

Phase 1
The Observer floats in the air, a fair distance above the ground. it doesn't move much, and only takes damage from Magic Attacks, as it is protected by a green shield. It attacks the player by summoning minions that move around like demon eyes, and phase through blocks. They have low HP (3) and low damage (3), and harass the player as they attempt to take out the shield.

Phase 2
The Observer's shield shatters, leaving the observer open to damage from Ranged Attacks. it will fire at the player with cursed flames. it will not take damage from magic in this state. when it has been lowered to 50 health, it will enter phase 3

Phase 3
The Observer starts dashing in at the player, and can only be damaged or knocked back with melee weapons. upon being knocked back, it will retreat a small amount before once again charging at the player.
