Judgement Shockwave is an ability exclusive to certain people in the final chapter of Fire Emblem: Radiant Dawn. There are 4 people who can use them. The first is Lekain, whose shockwaves can Silence all characters, but some can resist the shockwave. The second person is Deghinsea, whose shockwaves can give physical damage to all players in a 10-space area. The third is Sephiran, whose shockwaves can cause magic damage in a 10-space area. Ashera can use all 3, though she prefers to use Sephiran's.
