After going back to clear the harder blue circle fights in chapter 7, I noticed that they had become a LOT easier, even though my power had not gone up by that much. After checking the enemy power, I noticed that it had gone down drastically compared to when I was doing the instances at the first level you can (high 60's). For example, comparing the enemy power for the blue circle fight in Scout Deadwood Forest with a friend: Level 69 - 43,378, Level 77: 19,290

Does anyone know how this works? Does it also apply to ninja exams? It would explain why a lot of those low power ninja exam videos where they remove their gear to mimic lower power (but are level 80+) make the level look so easy. Also, I'm assuming this doesn't happen in pvp?
