He was about to join the beta test on the newest VR games, Second World. But an anomaly threw him into a world with familiar rules, a rule he usually only experienced in a game. Now he must use his past gaming experience in this new world. It was no longer a game, it was survival! A strive to reach the highest level possible. Equipped with dual-class of melee and magic user, Jack was set on the path to become the strongest character in this brave new world.
John started casting Summon the Eastern Lord after finishing summoning the mighty ape. The summoning spells of the Western and Eastern Lords had intricate runes in their spell formations, so it took him some time to complete the summoning. The time needed to cast these two spells was worth it, though. Once the mighty ape and the mutated saurian emerged, he could pretty much leave the fight to those two.
However, he didn't do so. He continued casting and summoning his other minions. They were the avatar incarnation, giant lizard, dirt golems, Fae, Armored Feral Tiger, and Water Elemental. Together with Steve, these summons formed a perimeter around John, Purple Mist, and Trinity Dawn.
John's Monster Overlord had a similar passive ability to Badass' Hell Ruler. All their summons were immune to being controlled or dispelled. Additionally, his Avatar Incarnation no longer had a duration. Its cooldown only began when the avatar was destroyed.
