Underwater Province Defense?

[HoneyBadger]

Yes, I want that too, in combination with the above.

Sure would be nice if everyone could at least get very basic (indigenous residents) PD underwater. It's hard enough to get into and fight properly in the water, but it's just depressing as hell when your opponent knows they can gobble territory back up with a lone scout or priest with impunity, because he knows nothing is defended.

And I'd go for some drowned sailors and creepy sea creatures that I may or may not have even ever heard of. >.>

Recruit local, non magical leaders in the underwater provinces. Give them a little bit of local chaff for support. Equip each of those leaders with Rod of the Phoenix, Spirit Helmet, Boots of Quickness, and whatever else you feel useful to keep the hero alive and functioning. Give them the battle orders; 'Cast Spells'. You won't need many to provide a very effective deterrent against invasion.
