3. version1.5.2
4. 1.17,with viaversion
5. Spigot
6.
Actually, those are jump + slow drop potions. I made them with commands.But when I created the kit "Valkyrie" and test,I found those potions became no effect.The same as leather armors.

This fireworkrockets used three firework stars to craft,but now them have no effects.

My English is not very good, if there is any wrong expression, please understand
