The monster moved and started the battle with a badass move, and William was well prepared for it.
"Activate the formations, trap this bastard here," William never planned to defend himself using any technique he had. Instead, he depended on his monstrous weapons to do such a task.
His monstrous weapons already built many arrays, making up a small formation around. The moment the monster moved, William gave the order for them to activate these formations at once.
The monster was a two element being, and that made it quite deadly. And yet it wasn't that hard actually to stop it. The moment William gave the order, and his monstrous weapons activated two types of arrays, built over wind and gravity elements.
Massive waves of gravity kicked in and pulled the monster down, and other waves appeared and wind blew like it was a raging wild storm, pushing the monster forward.
If facing other monsters, then such a way wouldn't work. But as this monster pumped its mass by using its elements and absorbed spirit power, it made it vulnerable to such attack.
The moment it got hit with such a wave the monster started to slow down its insane speed. William didn't move a muscle, only watched while that incoming rocket-like behemoth got stalled, until it stopped a few metres away from him.
"Hit it again boys, send it back to the hole it crawled out from," he waved his arm, while the monstrous weapons started to act again.
The best part of these weapons was that they weren't living creatures, and their spirit power supply came from elixirs. The monster could drain little, but not that much as it could only affect the spirit power slowly from nonliving things.
*Boom!* This time the monster didn't aim directly at him. Instead, it landed a few tens of metres away, causing a big hole there, and a violent explosion.
"What is it up to?" William expected the monster to come at him after hitting that hole, but it didn't. Instead, it retreated, then jumped again to cause another hole, and started on a spree of this.
"The holes are starting to form a circle, one that surrounds me in three layers... Fck! It's trying to make an array!"
It hit William right out of the blue. The monster just formed fifteen holes so far, and they looked as if they were forming three parallel semi-circular arcs around him.
When he realised this, he couldn't help but add a very important note to this monster; it was sane! He mistook that as it was born in this world, it'd be limited to be dumb and such. And yet it showed the same remarkable level of intelligence like the Nightmare monster.
Yet this was a very tough situation. He knew he safeguarded against the deadly threats from the monster, and the latter knew about how futile it was to keep coming at William using the old method.
So instead of wasting time, it started to think of another way to get to William. "I don't know what it's building, but it's not safe to stay here. However..."
This was the tough situation he found himself in right now. He built all his defensive strategy over him staying in his position unmoved. And yet staying here meant that he was risking everything.
He had two options now in front of him, either go out and take the risk, losing the base he built, or remain here and welcome whatever that monster was doing.
"Screw this, if he is building something, I'll also build something of mine," William didn't like either choice. And so he decided to make something different.
