The affected water becomes fouled and mildly poisonous, causing the following effects:

• If a creature drinks the affected liquid, they must make a Constitution saving throw or take 1d4 Constitution damage.
• If a creature with 2 or more HD swims or immerses itself halfway in the liquid, they must make a saving throw as if drinking the liquid.
• If a creature with less than 2 HD swims or immerses itself halfway in the liquid, they immediately die.

If the body of water mixes with pure water, such as a river flowing in, the effect diminishes, as follows:

• If the affected area is greater than 25% of the entire body of water, the water only deals 1d2 Constitution damage after 1 Day.
• If the affected area is greater than 5% of the entire body of water, the water merely tastes foul after 1 Day.
• If the affected area is less than 5% of the entire body of water, the water is cleansed after 1 Day.
