Even as the beast with too many mouths lunged at it with feral speed, the troll's instincts didn't waver. To it, the beast's mentality may have changed, but this was the same fight. The same brute it had been battering down blow after blow.
Seeing Dummy's body still slightly deformed, the troll's courage rose. It could tell that the beast's regeneration was barely applying itself anymore. Its intuition was instant, because that was how all trolls fought when challenging each other. It was always a battle of attrition, to see who would break first, who would collapse when their wounds stacked higher than their strength.
The troll's muscles bulged as it gripped its club, digging within itself to release a strength stronger than before. It had to kill the creature so it could team up against the bigger threat that just arrived.
But as Dummy aimed to crash into it, the troll lifted its club to smash the creature's head into the earth.
