Ancients Awakened/The Equinox Worms

"...2 big worms that control the flow of day and night..." The Equinox Worms are Post-Moon Lord bosses fought at anytime on the surface and consists of two worm bosses, the Daybringer and Nightcrawler. Fighting and defeating these bosses is essential towards the mod's progression, as they allow several Ancients to be fought.

Spawn
The Equinox Worms do not spawn on their own, and require the player to summon them using the at the. ,, and must be defeated prior to fighting the Equinox Worms, as they drop the , , and  respectively.

Behavior
Daybringer and Nightcrawler normally behave very much like normal flying worm enemies, flying through the air and attempting to ram the player. However, the main part of the fight is their unique gimmick of one worm having empowered attacks at certain times.

Once the Equinox Worms are summoned, the time of day will speed up similarly to the Enchanted Sundial's effect. Depending on the time of day, one of the worms will be empowered: becoming larger and unlocking a wider variety of attacks for the empowerment's duration. The Daybringer is empowered during the Day, while the Nightcrawler is empowered during the Night. The Equinox Worms will only use their unique attacks if they are currently empowered.

When one of the Equinox Worms are defeated, the remaining one will be empowered for the rest of the fight, locking the time into either the Day or the Night. When one of the Equinox Worms is defeated, time will still be sped up.

Daybringer

 * Frequently fires radiant arrows from her segments. These are fired perpendicular to the direction that each segment is going in.
 * Flies above the player, becoming highly resistant to damage, and rains down homing suns that eventually explode into rings of fireballs. Time will pause during this attack.
 * Throws out orbs that hover in place, before launching themselves at the player.
 * Creates several radiant stars that hover around the player and follow them around; after a short while, they explode into radiant beams that are telegraphed by warning lasers.

Nightcrawler

 * When empowered, immediately spawns a circle of dark clouds orbiting his head to protect him from damage. These will inflict Obstructed on contact with the player.
 * Casts night thunderbolts, which fly in a straight line.
 * Fires darkmatter energy blasts that slightly home.
 * Occasionally fires a barrage of fast dark matter scythes.
 * Slows down and starts curling in a circle while becoming highly resistant to damage, before firing deathrays out from his segments. Their firing direction is perpendicular to the direction the segment is moving in. The time of night will pause during this attack.

Other Notes
If they are spawned when the player is completely below the surface, the worms will flee, flying up into the sky where they will despawn. However, returning to the surface will cause them to target the player once more. Since both worms could despawn separately, the player could wait for one worm to despawn and go to the surface to fight the other.

The Equinox Worms drop one treasure bag each, but they share one bag type. Daybringer's bag drops when one Equinox Worm is killed while it is daytime, and Nightcrawler's bag drops when one is killed while it is nighttime.
