I always say there's 2 big things to Yone that affect his gameplay a lot. The first is playing around your 3rd q. This is so important because it gives you the mobility it gives you the knockup. The second is disengage, rengage this is the biggest part to Yone I always try to explain. you always want to try and disengage and then go in e and rengage for extra damage and a backup is things go bad.

So yea Yone's trades is E-3rdQ-AA-W-AA-E2. that's basic trading and chip damage in all in would look like E-3rdQ-AA-R-AA-W-ignite if needed-E2. see what makes Yone hard isn't his combos its how you use his e the best which ill be going into everything you can do with it.

im gonna finish this off but explain everything you can do with Soul Unbound, Yone's E.
1. when you recast your e it acts as a cleanse.
2. you can look around in it and face check bushes anything comes up just recast
3. assassinating key targets and getting back to safety
4. its acts like 1 30% dmg buff in a way the seconds you start 1v1 use e and make sure you use r before it ends.
5.you can buy items from the shop in your e so if your in base defending use e walk to the shop buy items then recast.

Yone is one of the best 1v1 in the game only losing to couple champs full build. but most are skill matchups like, Jax, Fiora, Mordekaiser.
well that's it anything I missed say it in discord.
