it looks like a dev tried shortening all the messages for each attack that hp/mp absorption gives you from an AOE down to just 1 message, but its wrote the wrong way. 21% of 128k = 26k each but get 260k 10 times. it was supposed to make the system window neat and clean but multiplied it instead. idk if that happens in pvp as well.
¯\_(ツ)_/¯
