Need some help understanding how attributes like Armor work

[Charon]

Hi, being new here I'd appreciate if someone could shed some light for me on the
1. Armor
a. How does it affect battles? What is the battle formula?
b. Armor can be increased only by wearing better "armor/clothes" or does any skill attribute to Armor as well?

2. Block
a. Block can be increased only by equipping better weapons or does any skill attribute to Armor as well?
Does Agility increase block? If not - how does it appear in the battle formula?

Many thanks

1. a) every 15 armour points decrease inflicted damages by 1
b) armour you have only from items, but warrior guardian have skill armour mastery which can increase it even by 22% as well by shield mastery if you use shields

2. a) block you have only from items ability, and is decreased by enemy strength, every 10 points strenth decrease block chance by 1%, and as well depends on difference level

Thanks a lot, Che! 

What about Agility? How does it work? Do I understand this correctly - 100 Agility will give you a 10% chance to avoid being hit?

[chegewara]

every 1 point difference between give 1% chance to evade chance and evade chance cant be higher than 75%

[Charon]

But why then Tip of the day says "Agility determines hero’s combat speed. Each 10 points to Agility grant 1% bonus chance to evade enemies’ attack." ?

this is old tip, which is not deleted yet. at the beginning it was like this tip said but has been changed

Great, thanks!
Do you happen to know what else is old in the tooltips info? How do the rest of attributes work now?
