Approaching Shadow (Eldritch Invocation)

You can lower lower the level of light by one (bright to dim, dim to darkness) in a 45-foot radius around you at will. You can choose whether this affects your own vision or not. The effect is blocked by one foot of stone, 1 inch of common metal, a thin shed of lead or 3 feet of wood or dirt. While the effect is active, you gain resistance against Raidiant damage and you can use your reaction to give one ranged attack against a creature (including yourself) in its radius disadvantage.
