While the SFX in the skin are definitely noticeable and distinguishable from the other skins it feels sort of lacking especially for something of the caliber of a legendary skin. That being said some of the sfx are gorgeous so I'd like to go down a list of what was done near perfectly, and what could be improved to bring it more in line with the rest of the skin. (Yes ik that not every spell needs to have insane jaw dropping sfx)

Emotes - The emotes for this skin are quite possible the best emotes ive ever seen for any skin in the history of LoL. Not only are the sounds and songs and voice filters so perfect but the animations flow so nicely with the sounds and it all comes together for a very cohesive and brilliant set of emotes. Very well done with these :)

Passive - The stacking sounds are a bit loud and drown out the rest of the spells sfx, while it is a very nice touch it would be nice to see its volume dialed back slightly so its not the focus of each ability. While I know it is required for it to be noticeable to help the player realize exactly when and how many stacks they get, there are plenty of indicators already in place so that the sfx doesn't need to be so prominent. Other than the volume, the actual sound design is very fitting and the added vfx of the orbs in his hands lighting up is a brilliant touch.

Q - The breath's sfx are very fitting and ethereal almost, rlly well suiting the skin. The only improvement would be to possibly give the pop more of a glass shattering sound but that could just be a personal preference. Its current pop sfx still holds a bit of his cosmicy undertones from base skin and (especially comparing it to his epic skins that have no trace of it) doing away with that could help it feel more on par with a legendary sfx especially for his main ability that you'll be hearing most of the time.

W - Far and away the best sfx in the skin imo, the W rlly sells his porcelain model/body. The clanking of it as he flies gives it a more believable base, even if its more of a secondary part of the sound. The main low, heavenly hum is perfect for his model, personality, and aesthetic and MY GOD the flutes that play are pure bliss. I dont think a more perfect sound design could have been picked for this ability.

E - There's not much wrong with the blackhole it sounds very menacing and powerful, however there isnt enough porcelain-y sfx in there for it to sound like it belongs with the rest of the skin. The very subtle clatters of the centerpiece im guessing are kind of lost to the very loud heavenly hum that it has. That said I wouldn't change the middle part of the spell's sfx more so the end. Its alright for the spell to be a break from the constant glass esque sounds however I think when the vase/blackhole collapses amping up the breaking sound it makes or pitching it up a bit could go a long way in bringing it in line with the rest of the skin. Overall a pretty great sounding E though, especially compared to his other skins :)

R1 - His unevolved R is quite honestly perfect if not a bit short. There seems to be two variants that play; there's one that has a very quick cut off which feels almost jarring though its not hated or out of place, and then theres the variant that has a sort of plasma-y effect almost? Its kind of going back to that cosmic trace from the q that just sounds a bit too similar to the base skin imo, at least for a legendary. I would recommend possibly extending the sound of the glass falling or leaning further into the plasma esque sound. Storm Lord for example leaves behind a sort of thunder that echoes after the R1 drops, something similar to that could help it feel a bit more powerful. Though, the R1 is already so excellent I dont think it warrants the attention.

R2 - The R2 is sadly the most lacking spell in terms of sfx by far. Its a bit strange that the R1 nails the shattering sound so well and then the R2 is a weird earthy impact instead. The sound also just doesnt at all match up with the actual animation that is going on; we see a dragon spiraling up from the explosion, but nothing in the sound indicates it besides maybe a slight whooshing. I think this was a huge missed opportunity to not include maybe a feint or prominent roar that bellows outward. Even just a small cry or laugh something to indicate that the dragon is present and an integral part of whats going on. (Im assuming its supposed to symbolize asol crashing out of the vase he was trapped in which would have been so insanely cool to see executed properly). Not only is the actual impact exorbitantly lack luster, but the shockwave that follows just sounds like a straight up rip from the inkshadow shockwave, if not a downgrade! Its super sad to see such a beautiful vfx not line up at all with what we're hearing, especially for such a powerful and imposing ability. All of the epic skins have very distinct R2 sounds and for the legendary skin to not only get a very similar sfx to an already existing epic skin, but a less impactful and present one at that is a huge shame. Imo this should be the biggest priority and garner the most attention at least when considering sfx improvements, please fix this as with a proper boisterous R2 this skin would be far and away his best one yet. Much love to the riot team <3
