From the eleventh floor onwards, Rank 4 monsters leading Rank 3 monsters appeared.

They were all groups of monsters that coordinated well with their allies, such as Kobold Knights led by a Kobold Mage and Rock Monkeys under the command of a Rock Gorilla.

And on the thirteenth floor, multiple Rank 4 monsters began to appear simultaneously. Even Vandalieu’s party began having some difficulty dealing with these.

When they encountered a group of Hell Hounds that kept their distance and spat flaming breath attacks at them, Vandalieu fired several【Mana Bullets】at them, turning some of them into lumps of meat, knowing that some of the Experience Points and materials would go to waste.

When multiple Rock Golems appeared at once, everyone had to go all-out with the use of their martial skills and then recovered their Mana through Vandalieu’s【Mana Transfer】afterwards.
