Fargo's Mod/Dungeon Guardian (Eternity Mode)

Eternity Mode Dungeon Guardian is significantly more powerful version of Dungeon Guardian with new attacks. It can be summoned by going below depths of 0 into the dungeon before Skeletron has been defeated, or summoned by using a while the time is day.

Behavior
Dungeon Guardian will always chase the player while repeating a pattern of five attacks: The pattern then repeats.
 * Spawns large amount of Bones from above Dungeon Guardian that rains down.
 * Releases rings of 6 Cursed Skull.png Cursed Skulls that homes in on the player after a short time. Dungeon Guardian will do this 2 more times.
 * Summons horizontal and vertical walls of massive Skeletron Head.png Dungeon Guardians and each wall consists of five Dungeon Guardians, that rushes in on the player, and despawns upon reaching the center. This attack starts with white lines as an indicator for each Guardian which indicates their flight path.
 * Creates an implosion of many smaller Skeletron Head.png Dungeon Guardians that centered on the player. This attack also starts with indicators similar to the last attack.
 * Casts many massive Skeletron Head.png Dungeon Guardians from above and below, however the guardians that spawns on the left side flies 45° to the left instead of going straight up/down, and that the Guardians spawn on the right side flies 45° to the right instead of going straight up/down. This attack also starts with indicators similar to the last attack.

Tips

 * Keep away from the boss at all costs as it's contact damage can instantly kill any unprepared player ignoring any immunity frames.
 * Spectre Enchantment, Cobalt Enchantment, and Mythril Enchantment are all very helpful contributing to the dps against it.
 * Pure Heart, Titanium Enchantment/Titanium armor and Hallowed Enchantment are helpful for survivability.
