Ragnar muttered, "This is it!" before charging straight at the troll. He scaled its massive form, using its leg, knee, and chest as stepping stones before reaching the head. With a ferocious yell, he swung his axe with all his might.
"Ragghhhhhh!"
The muscles in his arms bulged with a crack, their exertion a testament to the raw power unleashed. Steel met flesh in a devastating blow that severed the troll's neck, sending its head flying through the air.
"Strong, but not fast enough!" Ragnar grunted as the head rolled on the forest floor, rapidly desiccating and withering away as if time lapsed.
"Ha! You did it, Ragnar!"
