Cole was always finding new ways to use his techniques and more often that not, which was practically every time. Cole got the enlightenment he needed in the heat or battle. Which was why this time it was not powerful bolts or lightning that attacked the four tunnels he saw filled to the brim with Darklings, rather it was a buffet or extremely powerful wind.
The darklings were packed and smashed into themselves and crammed deeper into the tunnels. The power of the wind was powerful that the Darklings at the front were smashed into each other in a gory mess of blood and energy, enough destruction for Cole to realize that the Darklings attacking from within the tunnels were people.
