An Apocalypse descends—as a lethal super-virus wipes out most of the human population. It took less than a day for the world to change forever—bringing mankind to its knees. 

It’s a time of misery and death for most, however, there are some who are lucky. Zane Graves, who came across a “Blood Crystal” is given an ability: [Dead Man Walking]—which grants him a special power, and so setting him off on his path to the top!

Dead Man Walking: Living By Day, Dead By Night

While the effort to replenish the losses which Zane had suffered in his battle with Gwen was minimal, the time it took was far more grueling. Simply travelling to Reno alone took roughly an hour of his time.

After arriving at their destination, Zane and the girls would fight eight hours a day, nonstop, before returning to Gravestone, where they would rest. Only to repeat the process again early the next morning.

They spent nearly half a month doing exactly this. Focusing on their own personal development while their scouts searched for another nearby Tier I Horde King to fight, considering Gwen was far more monstrous than they could have expected.

Despite being level 25, Gwen was way beyond Zane's capabilities, who was at the same level. This must be the difference between a level 25 "player" and a level 25 Boss. Regardless, the group would need to improve their levels and equipment if they wanted to face such a monstrous foe.

Level 28!
