[Trails in the Sky the 3rd] Kevin Solo vs Cassius | Nightmare NG

Got bored and decided to do more solos again. This is the second of three that I've done as of now. There are two ways of doing this Kevin Solo, either spamming Grail Sphere or Spear of Loa, and I chose Grail Sphere. I'll go over the pros and cons of both.
1. Grail Sphere
Pros: Safe and Defensive
Cons: Passive and Grail Sphere has 35 Delay
2. Spear of Loa
Pros: Offensive and has 30 Delay
Cons: Need to play additionally safe
Since I didn't have a lot of Swingwiches, the second option would've better and would've prevented a lot of panicking, but it still worked in the end to my surprise.
As to why I focus on Delay on S-Crafts: I use them after Cassius uses Armor Rend to make sure he doesn't delay me to death, and the lower the S-Craft Delay the better.
