Touhou Luna Nights

This is the second boss. Story related, unmissable.

The homing knives work well in this fight. She has two phases. In her first phase, she has five attacks to watch for.
-She drops red mist, which can be avoided fairly easily
-She fires projectiles, which can be jumped around via stop time
-She drops bomb-like objects that move towards you and create a column which can damage you. Stop/slow time and get between them
-She flies high across the screen, then sweeps back low. Crouch and she will never hit you, plus you’ll get some graze points
-She creates a circle of glowing orbs that move around her in six lines. Slow time and walk under them or stop time and slide under.

In the second phase, around half health, she adds a corkscrew column of lightning. Slow time and navigate through it carefully. This attack does heavy damage. Her other attacks gradually speed up, and her orb wheel starts rotating the opposite direction. This makes it harder to slow time under, so stop time and slide seems to work best.

Keep homing knifing her and she’ll go down.
