Compressed

"I'll give it a try."

Atticus had considered various scenarios before stepping into the sea of acid. From the outset, it was clear that for beasts to survive in such an environment, their bodies must have adapted to it. He expected them to be incredibly durable.

With his elemental powers, Atticus wouldn't have worried about such beasts. But now, the only weapon at his disposal was his storm-like mana, which could shred enemies and track them relentlessly. It had been enough for the first and second trials, but the third? The katana wouldn't make it so simple.

So, he devised a solution.

He based his idea on the concept of domain fusion. Back during the battle with the branch heads of the Obsidian Order, Atticus had compressed his domain onto himself to concentrate its power. Domains spread energy too thinly, wasting vast amounts to cover a large space, just like his mana storm now.

The solution was obvious: compress the storm.
