Supreme Calamitas

Supreme Calamitas is a post-Moon Lord superboss that can be fought anywhere and at any time of day. She is currently the most challenging enemy in the Calamity Mod and is notoriously difficult, especially on Revengeance Mode or Death Mode. The player should be very well equipped both physically and mentally before taking her on.

Spawn
Supreme Calamitas does not spawn on her own and requires the player to summon her with the Eye of Extinction on the surface at any time. The Eye of Extinction is reusable, so Supreme Calamitas may be summoned any number of times. Her spawn quote will vary depending on the number of previous deaths to her.

Behavior
Supreme Calamitas will behave similarly to Calamitas, but with a new, extensive set of far more powerful attacks. She switches between these attacks at seemingly irregular intervals, though has a set pattern to her phases. She always remains either directly above or to the side of the player, only breaking position during Bullet Hell phases or during her devastating dash attacks.

Upon spawning, Supreme Calamitas will create a 253x253 (inner available area is 251x251) rectangular arena made of unbreakable Arena Blocks. Leaving it will cause Supreme Calamitas to enrage, speeding up her Brimstone Hellblasts significantly and giving her 99% damage reduction.

Attacks
While Supreme Calamitas is mobile, she will switch between these attacks at irregular intervals.


 * She charges at the player at an incredibly high speed, dealing massive damage. This typically occurs several times in a row.
 * Once she enters her second phase, she will charge half as many times in a row.
 * She shoots bursts of Brimstone Darts at the player.
 * She fires Brimstone Fireblasts, which home in on the player and burst into Brimstone Darts upon contact with blocks.
 * Once she enters her second phase, additional Brimstone Gigablasts are fired throughout the fight.
 * She launches Brimstone Gigablasts, which home in on the player and explode into a large ring of Brimstone Darts after some time.
 * Brimstone Gigablasts will explode upon contact with blocks during Bullet Hells, but the ones she launches won't.
 * She remains at the player's side and fires a barrage of Brimstone Hellblasts, which accelerate towards the player.
