Behavior
This topic is a WIP

Phase 1
Immune to traps

Limbs are completely immune to damage

Prime Cannon shoots cannonballs more frequently and periodically shoots Dark Stars

Cannonballs can hurt the player while airborne and inflict Defenseless

Prime Laser shoots a spread of lasers with better accuracy

All contact damage and lasers inflict Nano Injection.

Telegraphs spinning with a targeting reticle and in phase 1 only, summons 4 walls of guardians imploding on horizontal and vertical directions when it starts spins

Phase 2
Enters phase 2 at 75% life. In phase 2:

Gains four additional limbs that attack by swiping diagonally

Alternates between using Vice/Saw and Laser/Cannon arms outside of spinning, and spinning switches the attacking arms. Only 2 arms will attack at once

Prime Vice swings down at the player while Prime Saw quickly stabs from the sides

Prime Laser alternates between 2 spreads of lasers around the player and 1 spread aimed directly at them

Skeletron Prime moves faster overall and becomes much faster when spinning

Shoots rings of dark stars consists of dozen spreads of dark stars instead of rockets while spinning

Main limbs will stretch out and spin when Prime spins in phase 2, they can reach out further if you escape the circle

When brought to zero life, regains 100 more life, loses all limbs, and enters Dungeon Guardian mode, similar to skeletron in #|Eternity Mode.

Trivia

 * If the Eternity Mode Recolors option is turned on in the Mod Configurations menu, it resembles Gunmetal.
