Haze Ninja Art: Forbidden Technique: Hellish Obliteration

The user summons sludge in the area around him and those caught in the sludge will sink to their deaths. If the targets try to get close to the user, they will sink faster. The downside to the technique is that the user will sink first, making it less likely to kill other targets, making this technique more suitable for stalling than actual combat. However, the user can cancel the technique so long as they're alive.
