Deadly Sight

Deadly Sight is a power of the Dark Side, focusing the user's hatred into deadly energy.

With it, Darksiders can inflict pain and injury upon their foes merely by looking at them, causing a victim's body to burn and smoke as they die. With this power, the user can damage entire groups of foes within their field of vision. Tiring to sustain, it is inefficient in terms of the strain it causes on the user's Force reserves, but is nevertheless effective in the right situation.

It should be noted that Deadly Sight injures everyone that the user looks at, including allies; it is unknown whether or not it can be refined, especially because of its dark nature.
