not rolled by the roulette
Shield of Light is a retaliation shield skill that unleashes a wave of light in a cone in front of the user, dealing physical and lightning damage. If the wave hits an ally, it will unleash additional waves of light from them. The damage of this skill scales with your shield's defence values. This skill becomes usable after blocking a hit.
On an unrelated note, I did find S.H.I.E.L.D. really enjoyable.
Level requirement: 16.
The roulette doesn’t roll this gem, so its delivery options haven’t been worked out.
