Martian Saucer

The Martian Saucer is a large flying boss that spawns during the Martian Madness event. The Martian Saucer moves through blocks, and has four turrets with independent health meters that must each be destroyed before damaging the saucer itself becomes possible. The turrets include two rocket launchers and two laser machine guns. In addition, the saucer itself fires a large beam ("death ray") that can only fire directly downward, and which cannot be destroyed independently. The spawn rate is rare tho.

Behavior
The Martian Saucer has three attack modes and always moves a short distance between attacking. It cycles through these modes in this order: After the turrets and cannons are destroyed, the saucer stops and shakes for a moment as it becomes "enraged." In this stage, it alternates between going from your left or right towards yourself while firing its "death ray" for massive damage (175+ [need a confirmed damage output]). It also shoots out yellow flames that linger on the ground for a while that deal damage if touched, similarly to one of the attacks by Mourning Wood.
 * It locks onto your location and fires a volley of lasers at that location. This attack does not follow you if you move around.
 * It fires multiple small homing missiles from its cannons.
 * It tries to hover over you for a moment before unleashing its "death ray," travelling in the direction you were in.

Tips

 * To dodge its first attack, hover above or below its lasers. To dodge its second attack, run away from the saucer as it shoots so that most of the missiles hit the ground in front of you. To dodge its third attack, have it start shooting its "death ray" and fly over it, since it cannot change directions as it fires. Rinse and repeat to destroy the turrets and cannons.
 * The "death ray" cannot go through solid blocks so have some cover above your character. It is not easy attacking the saucer directly since it always hover some distance above the player so have minions and projective weapons to attack it.
 * Stay well hidden under solid blocks when it goes into the berserk stage. It is also useful to have a weapon that can go through walls in his berserk stage so you can stay safe.
 * It is easy to dodge the saucer during its berserk stage by moving away from the saucer wherever it is while flying. This means that the "death ray" can't catch up to you and that you don't touch the yellow flames.
 * The Stardust Dragon minion is capable of killing this boss without any intervention from the player.
 * Using any non-piercing arrows with the Phantasm can deal massive damage to the saucer.
