I didn't feel it that much when my replica used Ice Field which was more a movement debuff skill than a damage skill, but when I was hit directly, it really hurt even when taking into account my 30% reduction in damage of ice-type skills.
As a result, my health decreased drastically.
At that moment, I could understand the screams and shouts of pain of the enemies as they died from my attack. Given that even I was feeling this much pain, they must have felt a lot more pain that they definitely would not want to go through again.
Of course, my enemy replica and I fought differently.
I first used my AOE skill with a relatively long cooldown while my enemy NPC replica used simple skills such as the Ice Ball or Ice Bolt.
If we compared it to boxing, I aimed at knocking out my opponent with a heavy hook, while my enemy ate up my stamina little by little with repetitive jabs.
