Damage from such effects accumulates. It is only reset after everything else happens, as I've had troops gate in, fight a battle and then get hit by a site effect that does damage, finishing them off before they can heal. And we're talking heliophagus level critters here. Using FFTS and FfA on Jotun's is a waste of time, though, they are too tough for it to be effective. Everyone else (except Abysians) suffers badly from it, especially if you hit a hoard province (as I did in the Back to the Fray MP game, managed to wipe out half of Thufir's hoarding in a few turns by hammering up to five FFTS and a dozen FfA spells into a province of his that had troops I didn't want at my doorstep. Turned out his hoarders were in the same place...

As for Boron's numbers, that kind of clamhoarding is just...overboard. I mean, sure, it's nice to have massive amounts of gems and do whatever the hell you want magic wise, but for me at least it quickly takes the fun out of the game. Well, to each his own I guess.
