Astrum Deus [Terraria][Calamity][Revengeance][Master][Melee]
In Terraria (v1.4.3.6), playing the Calamity Mod using tModLoader, Astrum Deus is an optional boss that must be summoned using a Titan Heart at an Astral Beacon. Although optional, defeating him does unlock mining Astral Ore, which when crafted into Astral Bars, they can be used to create the Astral Blade, True Biome Star, Deific Amulet, Etherial Core (for mana users), Astral armor set, and more.
A long platform with one or two extra sets of platforms for resetting jump time are helpful. The Fallen Paladin's Hammer works well as does any piercing or true melee weapon that allows you to damage multiple segments. The hammer allows you to maintain some distance, which is easier, at the cost of reduced DPS.
