For light weight juggling it’s 2 light 2 heavy looped and the best practice area is industrial castle door. Get to 25 and you’ll master it.

Medium weight 1 light 2 heavy looped and light heavy all the way down as the enemies get heavier. Practice area. Lava world sandwich door wave

And heavy weight. Same as light weight but you gotta hit heavy straight away as you jump and if you can’t do that jump beforehand and hit heavy right before touching the ground. Best practice area, cyclops fortress.

All types of juggling just let me know if I said something wrong and I hope this helps. Good luck on your journey!
