Jack's Powers

The tip of the Spear protruded from the other side of the neck, coated in blood. 

The boar's huge body lay down a few centimeters from Jessy, she could see her reflection in its shiny tusks.

Even though dead that beast still had a bloody aura around it.

Everyone's attention was on the person standing on top of the boar's body and holding the half-exposed spear, while the tip of the spear protruded from the other side.

Its wounds were gushing with dark red blood tainting the ground below, wherever it fell small plants grew rapidly as if given some booster. 

Jessy slowly got up and moved closer to Jack while supporting Abella, John also helped Mey and Nanny up, and soon everyone was gathered around the boar's corpse.
