Skills
Crescent Moon - Charge for 1 second before sending a slash in a huge cone in front of him. Meant to be strong against ranged opponents but weak against anyone who's close to him

Dawnbreaker - Charge half a second before slicing downwards, dealing damage, knocking up, and stunning in a wide line in front of and behind him.

Fleet Footwork - Charge for 1 second before surrounding himself with windslashes that deal damage and slow. Also gain speed.

Martial Poise - Slow down for 5 seconds. During this time, any damage taken causes a circular slash to come out of the boss. Additionally, any damage taken from greater than 7 blocks away causes the boss to dash to the source of the damage, dealing damage to any enemies in the way at the same time. The 7 block radius is marked.

Zenith Blade - Can only be cast if target is within 5 blocks of the boss. Strike forward 8 times, dealing damage and slowing. If the target is below 30% health, deal bonus execute damage, which is indicated by a change in particle color and intensity. This skill is sometimes cast immediately after a few dash skills like a successful martial poise.

Setting Sun - Projectile that acts like a grenade (thrown upwards but with gravity and mildly tracks target), but instead of it being a grenade, a line is drawn between the boss and the projectile, making it a giant slashing ability. Easy to dodge as it's telegraphed, but tricky and may hit unintended targets due to how it'll swath widely.

Starfall - Marks multiple locations in the area, then charges for 2 seconds before teleporting rapidly between them all (at random) and dealing damage in an area around each.

Eclipse - When the boss deals damage a certain number of times, his eyes grow red. During this time, he summons two ghosts, who are just zombies that dont take damage and do melee damage. During this time, outside of his rotation, he doesn't move but instead dashes every second, dealing damage every second to any enemies that are in the way of his dash. He has a focus bar of roughly 5-10. Dealing damage to players heals this focus bar, but dashing through the ghosts damages it. When he's out of focus, he reverts back to normal.
