We pass bosses starting with twins, tk. the rest requires a jetpack, which can be purchased from the ferryman. She appears in the world after defeating one mechanical boss.
1 Gemini
You are required to minimize your time on the ground. Take off and landings on a regular basis. At the first stage, you do not need to run away from the boss, it is enough to move only vertically, occasionally changing the position to the left and right. We attack with the bow of Daedalus. In the second stage, you need to run away from the boss, carry out the attack continuously and the main attention must be paid to maintaining a distance from the boss (the speed of the twins will increase significantly). Also, it is advisable to focus on one eye so that by the middle of the battle you are not attacked by two reinforced ones at once.
2.Skeletron - Prime
The main role in victory is given to the jetpack, with which you can take off faster (by pressing the up key {w}). You should not stop firing with Daedalus' bow and move around the boss clockwise (or counterclockwise) with sharp ups and downs to maximize your chance to dodge attacks from the boss's hands.
3.Exterminator
Here you need to run away, keep a great distance from the barefoot and not cease fire. It is advisable to stay in the air for a longer time of the battle, because this boss has perfect control of the ground. Unlike tactics with other mechanical bosses, your movements should be smoother: you need to hover in the air and land on the ground when you are convinced that the destroyer is not heading for you, and then take off again. You should also give preference to the destruction of drones.

1.Arena
This guide does not require a specific arena. At most, bonfires and a heart lamp can be placed on the battlefield.
2.Errors
Aggressive attacks
Using a nurse to heal
Paying great attention to the health of your character
Ignoring boss attacks.
