This animated corpse is sopping wet, as if it just crawled from the water. The air around it is thick and cloying, exuding the essences of the corpse's watery grave.

The drowned lost their lives in the watery deep. The evidence of their gasping death always saturates their clothing and flesh, and fills the air around them.

Many drowned came to their current circumstances when their ships went down at sea with all hands. Others, more ancient, first arose when their island homes sank beneath the waves ages ago, drowning all.

A drowned stands between 5-1/2 and 6-1/2 feet tall and weighs between 120 and 210 pounds.

The drowned speak Common and Abyssal.
