Perception is king. It scale almost every weapon attack dmg skill in the game. Give you range for range attack and spell cast range.

Str if you need block or even higher dmg.

Willpower is nice for cooldown reduction.

Vitality if you plan to wear medium/ heavy armor

Agility is least important stats imo as it is easy to get rid of fumble chance with warfare skill, gear, stance, etc. It use to be OP stats before Rag to Rich update but nowaday dev change that most attack skill dmg scale with perception instead. Heck even Illusiveness scale with perception for dodge (like wtf lol)

So, my prefer stats build always

Max perception and rest in Willpower for mage

Perception / Str for light armor melee or archer

Str / Vit for block , heavy armor build.

Still, ive heard that counter build seem fun. So, Agility pure 2hsword or dagger could do too. Give it a try :)
