A void whelp summoned by Medivh from who knows where, a horrific monster called forth by Medivh from some unknown world, and of course, the Nightbane that Akanagos had transformed into.
The strength of these bosses was quite formidable, with levels mostly between 50-70, but compared to Medivh's own strength, they didn't seem that impressive.
Placed in a normal instance, they would be considered strong, but compared to the power of the heroes outside the castle, they didn't have much of an advantage. It looked like the first few bosses were just giveaways; only the final Medivh seemed to be overpowered.
Fortunately, as a hidden boss, even if he didn't trigger his boss form, he was still a neutral NPC; the monsters in the instance wouldn't attack him.
As Mo Fei made his way, he observed closely and thought to himself that it was a good thing he didn't choose to be a Crusader, for at his current 20th level Bronze tier four hero in human form, any encounter would mean certain death.
