The moment the Wyvern Cores merged into the Shelter's Barrier, the dome of mana rippled like water disturbed by a storm.
Soon, its glow intensified and just like that, arcs of energy started sparking across its surface.
Then, with a powerful shockwave, the barrier changed.
Whummm~
Lightning surged outward in waves, striking everything beyond the walls!
Indeed, the barrier had just become a barrier of lightning!
Zombies convulsed as bolts ripped through their bodies!
No matter what, lightning was still lightning!
Even with their high defense, they were affected by this attack. Soon, they were just charred flesh sizzling.
Needless to say, against the Vampires and Thralls, they were also incredibly effective.
Thralls shrieked as their hands and feet twitched after getting hit!
With the arcs of electricity around the shelter, they couldn't even get close!
