While traveling through the city, Raze had been observing the beasts and how they acted. At times, through different dimensions, he would encounter the same type of beasts he had beaten before.
That wasn't the case this time, but through entering a large number of dimensions with challenging beasts, he had learned that it was best to observe the enemy first.
There were a number of interesting things that a beast could present: another form, a special elemental power, or an unusual trait that could be used against them.
On his way here, he had figured that these beasts didn't have direct eyesight the same as themselves, and instead were relying on sound. With this, he had already come up with a plan to get rid of the majority of them, but he needed to get rid of the large threat first.
