Here are concepts for a ground up creation of "Jade Guardian Xayah's R." The color palette was influenced by Jade Guardian Renekton and Nasus while some shape language was also taken from Jade Empress Lux. Alterations for implementation are already floating through my head - Specifically for panels 2, 4 and 5, but that's the nature of something being a concept. The sphere will also not move during the effect due to the rules so please ignore that in the concept I'd created.
First panel is simply the indicator. I used a custom one, though I noticed the new valentine's Xayah skin uses the normal indicator that morphs into a custom one I kept this as is during implementation since it's the only time you see the whole indicator easily
When I was concepting I was doing a cursory glance at the effect and how it felt but for implementation I realized the 'feathers' that wrap around here are actually very rasterized images -- maybe taken from her skin's texture of her feathers from the cape. It actually has two separate spheres with different start delays, rotations and speeds although the difference is by mere frames. The actual 'tornado' of feathers was greatly cleaned up for Xayah's valentines skin and I am thinking of taking a similar approach in my own and using shape language like they did to indicate it being a 'Jade Guardian' skin. Like how the valentines skin uses heart shaped feathers for here which then become the plane that moves across from her during the ult.
Here is the simple build up of the two weapons sheen on her to give that beautiful moment of "things are gonna get real dicey boys"
I realized the shapes/feathers used in frame two will become these blue feathers shooting out above all the other effects. I wanted a bit of a sandy feel. I have later realized I'll likely clean that up since they aren't exactly SAND skins like Shurima but just colors very closely associated with that feeling. So something I'll be watching out for as I work on it.
Here we finally have the 'at rest' which is a bit of a lie as far as the actual game goes since we all know you don't want to be between Xayah and her feathers on the battlefield. I was thinking of using a 'guardian' icon. Nasus has a very obvious dog motif. Warwick actually has no animal related motif and instead uses a unique pattern as his fear activates for an impact and lux has her unique symbol from the cast vfx of her ult. All things I'm playing with in my head as I work on this the next two days.
