Rosalyne, Blade of Dusk

Rosalyne, Blade of Dusk is a boss added by Meet Your Fight. It can be summoned by using a Dusk Key. When killed, it drops 1 Violet Bloom, 1-2 Enchanted Books, and a mix of Allium, Pink Tulips, Lilac, Rose Bushes, and Peonies.

Behavior
Rosalyne floats above the ground and can pass through walls, similarly to a Vex. When targeting a player and not currently attacking, it tries to constantly stay a few blocks in front and above its target.

The fight is split into four phases, starting at phase 1 when summoned.

Phase 1
During the first phase, Rosalyne is encased in stone and appears with four Rose Spirits. Rosalyne is immune to all damage but will not directly attack during this phase.

Once all four Rose Spirits have been killed, Rosalyne produces an explosion and moves to phase 2.

Phase 2
During the second phase, Rosalyne randomly alternates between three attacks. All attacks do damage per sword swing.


 * Go near its target, pause for a moment, then rapidly swing its sword 3 to 4 times while continually advancing toward its target.
 * Circle a fixed distance around its target, then pause and charge at its target, swinging its sword when near its target. Then it may repeat a second time.
 * Slowly raise up for a moment, then charge at its target, swinging its sword when near its target or touching the ground. Then it may repeat a second time.

When Rosalyne drops below 50% health, it moves to phase 3.

Phase 3
When entering phase 3, Rosalyne summons four more Rose Spirits, like in phase 1, and continues the attacks from phase 2, but with a higher delay between attacks. While the Rose Spirits are alive, Rosalyne is immune to all damage and regenerates every.

Once all four Rose Spirits have been killed, Rosalyne produces an explosion and moves to phase 4.

Phase 4
In phase 4, Rosalyne uses the same attacks as phase 2 and 3, but with much shorter pauses between attacks and swings, while also swinging more times per attack. The first attack now swings 8 to 12 times (instead of 3 to 4), while the other two now repeat 2 to 4 times (instead of 0 to 1).
