Thanks for the suggestion, Ayman. Unfortunately, anything with the shiny effect, mount trails, etc is client sided and done via Unity. The sprites we create are basically 3 frame animations. Left foot forward, feet together, right foot forward. Given the limited space on the sprites, it'd be impossible to draw something that sparkles when the player is stood still or even moving. Should the opportunity come up in the future, we can perhaps discuss rare or hard to get items having a similar effect to shiny Pokemon. If you have ideas for clothing items in the meantime, you can leave them here and we'll see what we can do. :)
