Kolmisilmän silmä

Three-Eye's Eye (in-game name Kolmisilmän silmä) is a spider-like robotic miniboss, found deep within the Power Plant, bearing dangerous attacks and unique traits.

Behaviour
This foe resides inside of a circular arena, a bit down and straight left from the height of the Experimental Wand. It has 1250 health, along with immunities to projectile, explosive, melee, and fire damage. Therefore, the only sources of damage that will work are: Slice, Ice ,Curse & Electrical.

While not performing attacks, a projectile eating shield will follow the boss, which means that in order to reliably deal damage without getting too close you must wait for an attack.

It has two attacks: a burst of 10 rockets that quickly accelerate towards the player, each dealing 50 explosive damage, and a long, red plasma beam that expands after a few seconds, dealing 150 damage per second.

On death the main body explodes akin to a nuke, leaving behind a pile of metallic limbs and a special Spatial Awareness perk.

Trivia

 * The spinning rockets that Kolmisilmän silmä fires were inspired by a boss in the freeware indie game IJI.
