I've seen a few suggestions that there may be an aquatic race DLC in the future. That would round out the collection very nicely. Perhaps something like the pirate faction from Alpha Centauri's expansion pack? Or a bubble dome spell so that everyone can build underwater cities?

Barring that, you can have one ship act as bait while the other loots the monster lair. Generally I leave sea monsters alone since they are easily bypassed, at least, until I have flying units or units with enough DPS to take it down.
Hmm, I'll have to try them out. I played as the humans, and by the time I captured some undead cities and built them up to produce units I'd virtually won. My undead game is still in the opening phases. Ah, skeletons. Very Jason and the Argonauts.

I did have one face-palming brainwave: water walking. Cast it on a couple of my super-buff melee units, walk on out, punch serpents in the face. Why didn't I think of that during the game? I do love the way magic shakes up the usual strategic rules. I haven't needed to consider factors like this since Age of Wonders: Shadow Magic!

My main problem with sea serpents is that they have a very slow attack animation. There was a long stretch of my game where I had to sit through 2-3 minutes of sea serpents burping water at my cities, followed by 2-3 minutes of my cities shooting back. Doesn't sound like much, but it added up and became a real irritant. As fast as I killed them, more appeared. My ships had a high attrition rate and I couldn't manage to punch on through to destroy the lairs. I ignored the seas for too long, let the monsters build up a strong presence.
