The Fake Action Surge

Arad lifted the sword above his head, smiling as he clenched his fist on the hilt. The veins on his arms bulged a bit as the blade turned bright red, igniting flames.

The adamantine sword gets sharper the stronger you grip it, and it can absorb the magic channeled into it.

Alcott gave the sword to Arad since he didn't have any great magic to channel, and a simple sharp blade won't kill monsters with regeneration.

Arad could channel his void or the elements, and he has the strength to sharpen the blade.

CLING! One of the bandits pulled his sword as he saw Arad's foot digging into the ground. He was about to rush at them.

CRACK! Arad didn't rush. He jumped forward, swinging his sword. CLANG! The strike cleaved the bandit's sword and head in a single motion. The flames gushing from the blade seared the bandit's neck, preventing any drop of blood from leaking.
