The AR? Not sure I understand your question here.
Why Was it able to do the same attack that's mine but it's better can you understand it now
You mean you tied and the Monster did more damage to you?They have higher attack, so they do more damage
I think he tried to say that some monsters are unpredictable when they are in special attack
It's rank 4 and some rank 2 monsters
That's intentional, Special Attacks are either Healing or a Random Attack
