Hello everyone, I hope you're doing great.
This video was uploaded because I haven't really seen anyone do something like this so I thought I could give it a try (also serves as potential day 21 strategy for 1 hp playthrough that I may or may not do but who knows).
Timestamps:
0:00 Spawning Shadow Pieces
0:18 Fighting Shadow Pieces (Phase 1)
0:56 Fighting Shadow Pieces (Phase 2)
4:03 Fighting Shadow Pieces (Phase 3)
6:05 Killed Shadow Pieces
Since many no damage strategies for shadow pieces involve either using lazy explorer or playing a character that can teleport or using bone armor once fuelweaver is killed, I decided to scrap all of that and see if it's possible. As a result of my attempts here is this video.
Hope you enjoyed it and have a nice day!
