I had a lot of fun with this on a new playthrough. It's a bit too complicated (as expected) to be an always include in future runs (I'd rather just use the skins normally and the buffs themselves aren't THAT impactful) but as a one off it was a neat chain. Thanks for making it.

Any recommendations or ideas? There's not much I can do in terms of simplification though the buffs could be improved somewhat

I can't see making the move speed buff any stronger being a good thing, but if you instead made some of them affect other stuff it might be good. For example instead of making each tier give move speed on both styles unlocked at that tier maybe one style increases hand crafting or mining speed instead. Those would also not be so game breaking that they would be must includes but would make the choice a little more interesting.

I'm planning on moving the mod away from timers and onto using an estrogen blood concentration level simulation, this means I can't have ester specific buffs. I can still add crafting and mining as overall buffs, though. That likely isn't completely satisfying so I'm still looking for other additional solutions
