Calamity Post-Moon Lord Progression Checklist

Overview

Defeating Moon Lord in Calamity is the halfway point, not the end. The post-Moon Lord progression is where Calamity truly shines, with 10+ endgame bosses, each requiring specific gear and preparation. This checklist covers the optimal order.

Profaned Guardians → Providence

First post-Moon Lord bosses:

• Profaned Guardians — must be fought in the Hallow or Underworld
• They're a warm-up for Providence
• Providence, the Profaned Goddess — fight in Hallow for fire attacks, Underworld for holy attacks
• Holy attack variant is generally harder
• Drops: Holy armor materials, Profaned weapons

Sentinels of the Devourer

Three mini-bosses that unlock the Devourer of Gods:

• Ceaseless Void — spawned in the Dungeon, teleporting boss
• Storm Weaver — spawned in Space, long worm boss
• Signus, Envoy of the Devourer — spawned at night on the surface
• Each drops Cosmilite Shard fragments
• Must defeat all three to summon the Devourer

Polterghast

• Spawned in the Dungeon post-Moon Lord
• Three phases with increasing aggression
• Drops: Phantoplasm, used for high-tier crafting
• Can be fought before or after Sentinels

Old Duke

• Caught by fishing in the Sulphurous Sea with a special bait
• Extremely aggressive — one of the hardest pre-DoG bosses
• Drops: powerful fishing-themed weapons
• Optional but drops are very useful

Devourer of Gods

• Requires all three Sentinels defeated
• Massive worm boss that teleports through portals
• Two phases — second phase is a DPS race
• Drops: Cosmilite Bars, some of the best equipment in the mod
• Build a large open arena with multiple platforms

Yharon, Dragon of Rebirth

• The Jungle Dragon — fought in the Jungle
• Two phases with fire attacks covering the arena
• Drops: Yharon-tier weapons and Auric Tesla materials
• One of the most mechanically demanding fights

Exo Mechs

• Three bosses in one fight: Thanatos (worm), Ares (arms), Artemis & Apollo (twins)
• You choose which to fight first — others join at health thresholds
• Requires Auric Tesla tier gear minimum
• Drops: Exo Prisms for the absolute best weapons

Supreme Calamitas

• The final boss of Calamity
• Bullet-hell style fight with complex patterns
• Multiple phases, including a Brothers phase and final form
• Drops: Shadowspec Bars, used for post-SCal items
• Expect dozens of attempts — this is the ultimate test

Post-Supreme Calamitas

After SCal:

• Craft Shadowspec equipment — the absolute endgame tier
• Adult Eidolon Wyrm becomes a full boss encounter
• Draedon's arsenal unlocks additional Exo Mech content
• Achievement: you've beaten Calamity
