What generates gems?

[Edi]

Thanks for mentioning that those gem producers are not listed, because they should be in the special column. It's been a LONG while since I added anything with an ID less than 1700 into the DB, so this sort of reports are good. I'm not infallible, so reports like this are the only way to get this sort of oversights noticed.

And as Endo said, exemplary performance right off the bat. Having the unit number means I can immediately find what I'm looking for.

In the op list you forgot to mention that some spells generate gems.
Most on a per turn basis (Gale Gate, ...), but some others too, like the air spell that converts corpses into death gems (which I don't believe anyone uses btw).

I did forget about them. I'm not too fussed, they are well documented (I think).

Raven Feast (A4 Conj 5, 4 gems) is actually fairly good. It's a very niche spell but for 4 gems you clear out all of the unburied corpses in a province. The death gems are just a bonus. You will very rarely need to clear unburied corpses but for 4 gems and some lost research time you can slow down undead races.

I've also used it as an air nation trying to diversify into death magic. It can get you gems for Dark Knowledge cheaper than alchemy. Not a major source, but if you've got Air gems and you're thinking of alchemizing to get Death...

Whenever possible it's better to use those corpses for casting carrion reanimation.... unless your opponent has acquired and can use undead mastery.

Luck scales will generate gems.

Quantify that please.

At least once?
