Two Tons swiftly shifted his position and kicked off his back foot as he accelerated towards the Ouroboros. However, he knew that there was no way that he would make it in time. The one thing that he could not understand was how he had managed to lose aggro in such a short period of time! Not only that, but he lost aggro to someone who had not even once attacked the Ouroboros.
The only explanation Two Tons could think of was that the Ouroboros possessed a skill that made it so that it ignored aggro. While such a skill was not uncommon for boss monsters, if one was not prepared to deal with it beforehand then it could quickly shift the course of battle and force them into an unfavorable position just as it was currently doing.
