The powerful Reaper Guard

Alex stood still, watching as the forty Monarch level undead charged forward. Various domains unfolded, crushing the invisible enemies despite their stealth.

Seeing this, Xiao Mu and Xiao Hui also joined the fray. These ants were precious experience points, and if the undead killed them all, how would they level up?

Countless man-eating ants died instantly, their shattered bodies becoming visible before being summoned as undead by the necromancers.

In less than a minute, the original forty undead had multiplied into thousands, charging at the remaining man-eating ants.

Even though the undead couldn't see their targets, it only affected those with single-target attacks. For undead like Ethereal Wraiths, which dealt area-of-effect soul and curse damage, invisibility was meaningless.

On the battlefield, a Skeleton Warrior, unable to see its enemy, still charged forward, heading straight for the king and queen ants.
