A few people on discord mentioned that in skywars its difficult to tell if someone is using spellbooks of swiftness, or speedhacking. So i think there should be some sort of particle effect/sound that anyone can hear when you use a swiftness book.
I can usually figure it out because it runs out after 5 seconds
What I’m saying is that somebody could use speed hacks intermittently throughout the game
The reporting feature is coming soon so I guess report on the discord
