Bewitching Syndra for Pony. Can generate both normal and mature images.
Very little source material (beyond the game model) but eh, it worked out.
I cannot believe League has so many asymmetrical legwear skins (or maybe it's just bias on my end). As per usual, SDXL is mediocre at generating that, so you might need to use (x:1.5).
As is often the case, a lower CFG scale is recommended for realistic images.
