Alien

Aliens are very dangerous boss Mobs found primarily in the Mining Dimension, mainly in Caves. They can also be found in Alien/WTF? Dungeons, which are also found in the Mining Dimension.

Summary
Aliens are very aggressive mobs that arguably, have one of the highest speed of any mob. They will put out any nearby Torches, making the cave that they are in very dark, and easier for them to strike.

When noticing the player, feathers around their head will pop up, similar to a Peacocks, and they will charge at the player at high speeds, and will commonly circle the player, confusing them in a way. Once they die, they will make an ear piercing screech so the player should leave the area when killing the mob. This screech will also last for a long period of time, once the Alien is killed.

How to Kill
This creature is extremely, quick making bows not very effective against it. The best way of killing it is getting it trapped in a source of water, and using a low knockback sword. If there is no water, your best chance is to simply spam your sword in hope to stun lock it in place.

Equipment
When fighting an Alien, the recommended equipment is an Amethyst Sword, or a Ruby Sword and full Amethyst Armor or Ruby Armor. When fighting a group like in a Alien/WTF? Dungeon. An Ultimate Sword and at least half Ultimate Armor and Ruby Armor.
