True Seraph, The Forsaken Conqueror
Boss Patterns
100% to 80% | Seraphim teleports to 5 areas of the arena, each time firing projectiles at the previous location after teleporting. Throughout this phase, constant sources of bouncing projectiles are spread throughout the arena. Hardmode increases the amount of projectiles he shoots and how often he teleports.
Guaranteed at 80% | Seraphim flies across the arena in a straight line, creating two waves of projectiles at the end location. Seraphim is invincible in this phase. Hardmode makes this phase twice as fast however contact damage from seraph is removed.
After 80% health True Seraph starts performing different attacks which depends on RNG and these are the following:
True Seraph slowly moves towards a person while summoning celestial beams which deal 30 base damage if you stand in one when it expires, he also shoots feathers all around him three times and projectiles spawn on the sides of the arena which then fly towards the zone in which you can stand. Hardmode just makes him shoot 1 extra set of feathers and increasing the density of celestial beams by a bit.
True Seraph flies in the air and starts throwing poisons which when reaching the ground, makes a small particle effect and then explode dealing AOE damage, during this phase around the edge of the arena eyes appear and then a cross stabs them, summoning projectiles all around it. Hardmode makes him throw poisons twice as fast.
True Seraph Flies into the sky near the middle of the arena by 5 blocks and starts summoning an onslaught of celestial beams all while projectiles appear occasionally in the arena. Hardmode makes the beams appear faster and well disappear faster.
True Seraph Pulls everyone into the middle of the arena. Waves of celestial fragments approach the player in a sinusoidal manner of moving. Players must find the gap in the wave to avoid being damaged, and on top of that True Seraph starts summoning celestial beams which needs to be dodged aswell.
20% | True Seraph triggers his final phase, enclosing the arena in beams and having projectiles fire from all sides of the arena. In addition, True Seraph fires a volley of shots at the player, indicated by a red laser that summons the shots after a few seconds of spawning, and after the shots True Seraph teleports to the location of where the shot was and shoots feathers all around himself.
10% | Becomes invincible for a few seconds.
