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 player can damage the core only if all four turrets have been destroyed.

Behavior
The Martian Saucer has three attack modes it cycles through in order. It always moves a short distance between them.
 * 1) The Saucer locks onto your current location and fires a volley of lasers at that location. This attack does not follow you if you move around.
 * 2) The Saucer fires multiple small homing missiles from its cannons.   LOL!
 * 3) The Saucer positions itself above the player before unleashing its "death ray," traveling in the direction you were in.

After the turrets and cannons are destroyed, the saucer stops and shakes for a moment as its core becomes exposed. The core may be damaged during and after the transformation. In this stage, the Saucer will fire only its death ray, always moving towards the player. The death ray deals massive damage, even to those with Solar Flare armor. It also fires yellow flames that linger on the ground for a while that deal damage if touched, like one of the attacks of the Mourning Wood.

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 avoid its third attack, as well as its final enraged stage, simply stand under blocks.
 * A very easy way to defeat the saucer's second stage is to create either a ceiling or bunker thick enough to block the laser and use a weapon that can pierce through blocks or fires from the skies. For mages this involves a Meteor Staff, Blizzard Staff, Nimbus Rod or, should the player have obtained it already, the Lunar Flare. Rangers can make use of a Daedalus Stormbow and while Holy Arrows aren't necessary, the stars they produce can deal a significant amount of damage. Melee characters are limited to either a Death Sickle or Solar Eruption; however due to their limited range, landing a hit on the saucer can prove very challenging. Summoners with a Stardust Dragon or Stardust Cell can easily sit the fight out. A Frost Hydra or Stardust Guardian can also be placed on top of the ceiling for some extra damage.
 * 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 it produces.
 * With a decent weapon and armor, such as Nebula Blaze with Nebula Armor, the Martians may be killed quick enough to prevent the spawning of the Martian Saucer.
 * If the player is encased in any type of structure that is big enough to negate any splash damage from the rockets, the fight will be completely effortless. With a 1x1 hole for a Yoyo to fit through, even a Wooden Yoyo will be able destroy the Martian Saucer. However, this will take a great deal of time.
 * Unlike most bosses, the Martian Saucer does not possess any attacks capable of penetrating blocks. This can be exploited by latching onto the boss with the Piranha Gun and quickly going inside a safe area. You will need to repeat this when the boss enters its second stage, but for the most part, you can simply wait as the Piranha Gun continuously deals damage while the boss is unable to attack you.
 * If the "Wet" buff from Cute Fishron is activated (or the player is below half health), you can fly away slightly faster than the saucer can chase you.
