Gunner simply swung his hand and pulled over the dazed wights one by one before he punched them into smithereens. He decided not to waste any time since he could feel his Stamina burning away like paper in a fire, and he would soon lose his Explosive Strength's abilities.
The duo had both assumed that Gunner would practically never lack Stamina, hence he barely any Common stamina potions in his inventory. For now, the half-giant took many of them out and poured all of them down his gullet at once while 'pulling' a wight over.
He then tossed the bottles away as he took a deep breath and gave the struggling enemy a punch to remember, smashing its cranium open and preventing it from making any further movements.
Although his Stamina had been somewhat replenished, it continued to be drained at an unprecedented rate, so made short work of his foes before he ended up tapped out.
