This is probably one of the best texture packs in Minetest. It has a unified theme and feel that really makes Minetest feel like a classic JRPG. The fact that it has pretty wide mod support is the cherry on top.
Hands down has the best textures for armour out of any Minetest game - each set looks like a real set of armour with a distinct style and flavour. If you're designing armour for your own texture pack or mod, this is the standard you should aspire to meet.
Even if you don't want to play with the full texture pack, the 3d_armor and other components are modular enough that you can even make a remix for your personal use by dragging their sub folders into your desired texture pack. But then again, if you do that you'll miss out on the rest of this great texture pack.
