Question 2

Thanks to the new event, I changed Mabek's attack to "Challenge", which gives him 120% dmg but it makes him target the healthiest enemy. "Punish" says that his attacks target the last enemy that damaged him, though. Does this mean he attacks with 120% dmg the last enemy that damaged him? Or does the 120% only count against the healthiest?
Also, Mabek's using Giant Shortsowrd + Pulverizer, which makes him attack another enemy in the same row as the main target. Does the 120% count against the other one too?
Lastly, how does the 20% count? Is it 20% of the initial 100? Or does it count as 20% of the dmg he would inflict with the bonus of the giant's pulverizer?
