Anger!
His eyes were blazing with immense anger as he looked at the ridiculous debuffs that were enhanced by too much, to the point that they might even be capable of affecting him!
Yes, he had Infinite Mana. But taking 30,000% more damage from his enemies was entirely ridiculous.
That was 300 times the damage that he would be taking, which was extremely terrifying when one thought of the Incarnations of Chaos that could release power above what most Paragons only dreamed of. There was also the -30,000% to the Resistances of laws and Daos, meaning that the damage would come across even more as the future battles were bound to be tedious and dreadful.
This wasn't to even mention the "-75%s" to multiple statuses that filled the Corruption of the Usurper and even the myriad of debuffs added under the [Malignant Madness](Advanced) effect!
