Just added new stat icons and reworked how they're shown in Menus too~

I dig the style, even though I'm not 100% I won't do more changes to them in the near future.
Pieces of equipment now also show the stats they provide in a more compact and readable way! I've also added the variance (the "+-" icon) to the description, as it greatly impacts the final stats your weapons and armors have.
Shortly, if you've got an armor with +2π‘οΈ and a variance (+-) of 1, the final Toughness provided can range from 1π‘οΈ (2π‘οΈ - 1) to 3π‘οΈ(2π‘οΈ + 1)!
That's a lot of π‘οΈ!
