"Allow me."
Drek approached a tree of appropriate size near the riverbed. Sizing up the trunk, he made a rough mark in it with his axe to mark his swing. He readied his axe and a surge of pulsating purple energy began to infuse the blade. He takes a mighty hack, and a rip of energy bursts forth from the blade when it contacts the tree's bark, violently blasting through the trunk and sending a cloud of debris flying back into Drek's face. The tree totters on what's left of its stump, before falling forward with a little guidance from Drek and making a slightly splintery bridge across the river.
