Aspenth must be defeated to release Gjall, Heimdall's horn. He lives within Mimer's Well and has the ability to force the air out of your lungs and decrement your constitution by biting chunks out of your abdomen.
Read your messages. If you read that you must surface soon, ascend instantly. You cannot zap, throw, breathe rays (if you are a ray-breathing monster), or use fire vision underwater. Do not go underwater with too much weight, as you will sink like a rock despite knowing how to swim.
