It is still being worked on, slowing down due to holidays and classes. Actually, the description is way outdated and I need to update and add the new features.

That said, the last 3 skins are as follows:

All of them have most runes enabled by default.
Orange ('JJ') - Much faster, can attack out of shield instantly, Hitting enemies hard enough disables gravity for a time.
White ('Gojo') - Even faster, infinite dodges, passive repel of players and projectiles (hold shield for stronger effect)
Herobrine ('you know, i think i like that name') - DTILT fire spreads forward along the ground, starts with obsidian + diamond tools, natural projectile immunity.
