Wave of Filth

Creature must pass a Wisdom DC14 Saving Throw to avoid being targeted.

The targeted creature falls into hypnosis as what they perceive to be a gigantic wave of contaminated water rushes towards them. The creature is then knocked prone.

Prone:

• A prone creature’s only movement option is to crawl, unless it stands up and thereby ends the condition.
• The creature has disadvantage on attack rolls.
• An attack roll against the creature has advantage if the attacker is within 5 feet of the creature. Otherwise, the attack roll has disadvantage.
