To determine the probability of an attack landing, the following formula is used: Chance of evasion = Target evasion stat / Attacker hit chance stat So for example, it the attacker has a hit chance of 144 and the defender: evasion 35, that gives: 35 / 144 = 0.24 or 24% chance of evasion Naturally this means the attacker has a 76% chance to hit Knights (and barbarians if they decide to carry a shield) will also have a chance of blocking the attack. This is calculated in a similar way.
