I see, also I tried it out and I defeated the boss in one hit, without doing any other attacks, just like it said which wasn't exactly what I expected but it's cool to know it's possible. The issue is now that I didn't clarify how it's possible to do so in one hit. I say this in hindsight after doing it myself. The freedom to explore options in battle is what I like and I don't want to dictate but just imply the player can do something one way or another.
I think your talking about the canister right? I did it on purpose but I can see how that is jarring.
I'll check the stream out then.
