Kagemitsu

Info:
A samurai clad in midnight-black armor, dual wielding two katanas. During his second phase, his armor will turn white.

Boss Room:
He resides in a pitch-black temple, with dark tendril-like thingies sprouting from the ground. During his second phase, the temple will shift to white, and the tendrils will retract, growing trees instead of, yknow, tendrils.

Attacks: (First Phase)
Shadowstrike: He will teleport to the player, and strike him with one of his katanas, dealing 5% of their HP. He will then rest for like 5 seconds.

Dark Moon: After that, he will summon a ball of darkness and throw it at the player, dealing 10% of their HP, and regaining 5% of his HP.

Lightless Slash: After that, he will slash the player for 5% if their HP. He will then rest for another 5 seconds.

Black Dragon: After that, he will summon a dragon made out of shadow and throw it at the player, dealing 10% of their HP. He will then rest for 5 seconds.

Cataclysm: After that, he’ll use his two katanas and slash the player, dealing 25% of their HP and inflict the [Shadowburn] debuff, which takes away 1% of their HP each tick, lasting 10 ticks. Every tick is spaced out by 10 seconds.

Now, he will continue this until he hits 40% of his HP, and when he hits the 40% HP mark, he will enter his second phase. During this ‘second phase’ thing, his armor will turn white, and the boss room will change its appearance.

Attacks: (Second Phase)
Divine Strike: He will teleport to the player and strike him with his two katanas, dealing 10% of their HP. He will then rest for 5 seconds.

Blinding Slash: After that, he will slash the player for 5% of their HP and temporarily blind them for 3 seconds.

Judgement: After that, he will teleport to the player (again), and hit the player with the blunt side of his katana, dealing 10% of their HP. He will then rest for 5 seconds.

Radiant Sword: After that, he will call down a giant sword made out of light and throw it at the player, dealing 15% of their HP.

Lustrous Blade: After that, he will rest for 5 seconds, and after resting for a while, his damage will be buffed for 2x of its original amount for 5 attacks, and his katana(s) will be covered with light.

Trivia:
Kagemitsu’s left katana is named 影 (shadow), and his right katana is named 光 (light).
