Aberrant

The Aberrant roared in fury and pain as its arms fell off, but in the blink of an eye the arms regenerated, creating muscles, forearms and fists as quickly as possible.

Victor clucked his tongue, indignant at such power, but at that moment he realized that the Aberrant in general seemed to shrink considerably in size and mass as it regenerated.

"So, does that mean you have a regeneration limit?" Victor asked aloud.

The monster, desperate, launched itself towards Victor with a disorganized lunge, trying to grab him this time. 

Victor quickly dodged the Aberrant and saw an opening to attack his opponent, so he decided to take advantage of it. With one swift movement, he advanced towards the monster, taking advantage of the split second in which the Aberrant was off balance due to the failed attack. His sword cut through the air with a slashing sound, aiming straight for the creature's chest.
