The Corpse Incarnation of Vol Ming, Marut, was a Tier 3 NPC Boss. The most fearful thing about NPCs was that they learned from the battles and adapted to Player's skills and Vol Ming was only a little lacking in this department.
The team only needed to hold on for two minutes but those 120 seconds felt like an eternity because of how fast the Boss adapted. Necromancer Vol Ming raised another sea of Undeads to divert the firepower of the team and these summons were much more powerful than the previous ones!
The Army Samar faced previously had an infinite number of Tier 0 Troops but this Undead army had a sea of Tier 1 Troops!
