Terraria Wiki → Skeletron Prime
Prime Cannon - Flies behind the boss, trying to stay close to the player. Every few seconds, it fires a bomb that flies through platforms and explodes upon hitting a solid block. The bomb does not deal damage on contact. It is not particularly dangerous if you are fighting the boss on platforms or in the air.
Prime Saw - Slowly flies behind the player, constantly trying to "saw" them. If it catches up with the player, it tries to stay there, dealing constant damage. One of the most dangerous arms, as it deals quite a lot of damage, and once it reaches you, it is difficult to get rid of.
Prime Vice - Flies behind the player, occasionally attacking them with piercing blows. Quite a dangerous arm, due to the fact that it deals relatively a lot of damage and is difficult to hit. However, its attacks are quite easy to dodge. Her metal "vice" grips are animated—they bend and unbend every 0.5-1 second;
Prime Laser—flies behind the boss, always aiming at the player. Every 2-4 seconds, it fires a red laser. Its touch poses no threat, but the laser is very dangerous, as it deals a lot of damage and is difficult to dodge. This arm is also very difficult to hit, but it has the lowest health and defense of all the other arms.
Since version 1.2, it can appear at night, and the message "The air is getting colder around you" will appear.
