Story Background
"The Astrum Deus served as the guardian of the cosmos, before it succumbed to the Astral Infection. Following its demise, its soul would recover material from the surrounding infection, in turn reviving itself with a new body to inhabit."
Quote from: Calamity Wiki
- No one knows where he appeared from, as if he had been there since the universe opened - Is described as a blue river entwining the Milky Way, its length can stretch to hundreds of light years, its power is likened to a source capable of destroying any planet it wants, that is. perhaps until it weakens.
In Game
Astrum Deus // 300Hp
Astrum Deus Clone (Will Spawn when Astrum Deus less than 70% HP)
To summon the Astrum Deus, you need to have an item called "Titan Heart" which you only can get by killing the "Atlas", after all of that, put the item into the "Astral Beacon" in the top of the "Astral Tree".
/// So where is the Atlas? ///
Atlas will spawn in the overworld at night or in a cave like other monsters, but even that thing, Atlas is not a good choice for people to kill with just a Diamond Sword. Make sure that you have enough armor before fighting with him.
Atlas // 100Hp
Atlas has a 80% chance to drop the Titan Heart when it dies.
Titan Heart
(can be stacked)
// Where are the Astral Beacon and Astral Tree? //
Astral Beacon
Astral Beacon can be easily found on the top of the Astral Tree.
It is a tall tree without any leaves, it will spawn in all overworld and can be found easily.
