In this post I'll be listing the numbers you need per level in each stat for each piece of equipment to use it. This is the first time I've seen all of the numbers for every armour type and weapon type. These numbers are rounded up to the nearest half-point as to avoid confusion.
Light Armour: 1 dexterity and 1 strength per level
Arcane Armour: 0.5 strength and 1.5 magic
Heavy Armour: 0.5 dexterity and 2.5 strength
Axe: 0.5 dexterity and 3.0 strength
Polearm: 1.5 dexterity and 2.5 strength
Swords: 1.5 dexterity and 2.0 strength
Fists: 2.0 dexterity and 2.0 strength
Daggers: 3.0 dexterity and 0.5 strength
Magical Instruments: 0.5 strength and 3.0 magic
Soulspheres: 0.5 Strength and 3.5 magic
Bows, Crossbows, and Slingshots: 0.5 strength and 3.0 dexterity
Take these numbers and make your own builds with them, it's pretty fun.
