"Unless she is completely killed during one combat round, she will heal all her wounds". This is part of the description for Limne, or the two other Queens for this matter. It should be a separate ability from their Regeneration (that is weaker for the Queen of the Lake and the Queen of the Sea, and not yet equal to 100% for the Queen of the Deep).

Since this ability does not work for the Queen of the Lake, I would say it is quite likely the same goes true for the Queen of the Sea. Still, I should check it out one of these days. Testing this ability for the Queen of the Deep would probably be too difficult given her very high natural regeneration.
