Accuracy/Evasion does this build only works for monsters?

I notice Tantra/Kathana works differently than other games in terms of accuracy/evasion. I notice players with Accuracy = 600 still able to hit players with 1200 evasion without a miss as long as there is no level gap. Can give a detailed guide on how accuracy/evasion works in this game?

But at least 600 accuracy(of attacker) vs 1200 evasion(the attacked player) is a very big gap right? Is it not by comparison on attacker's accuracy vs the other player's evasion?

Oh so level gap. How is it calculated GM KZ? If attacker has a higher level, it will ignore the accuracy/evasion comparison and all attacks will not miss?
