Wish you could turn back time? To the good old days? Well, now you can.
I took some (200+) splash arts from season 3 to season 6 (with a few exceptions) and made this lora.
Use tag oldest for old-school art style.

Use tagnewest for the art style of 2015-2016.
league of legends is a trigger word.

official alternate costume is a danbooru tag that might make output more interesting, worth to try.

Useful tags: yordle, holding weapon, orb, monster, dynamic pose, from above, from below, foreshortening, dutch angle

I suggest using less quality tags for old-school art style to shittify the result. Otherwise it'll be too good to pass as old-school lol style 😁
