225 or 250 armour is the best trust me
Or ..... If ur low in dmg overall if u get it u can take +10 all stats or 5% stats and 150 armour
Or....... 150 health and 150 armour is also very effective.
Or ....... + 20 all stats which is very rare and expensive.
Armour % don't really give you a huge boost but they cheap actually.
So I'd prefer u take % all stats and % armour
