Gem-generating globals

[magnate]

Not sure if I'm being thick, or whether there isn't a global enchantment that produces nature gems. I've found the following:

Gale Gate (Thaum 8, Air 5, cost 60 air) - 20 air gems/turn
Eternal Pyre (Ench 6, Fire 6, cost 80 fire) - 20 fire gems/turn
Stellar Focus (Ench 7, Astral 5, cost 30 astral) - 5 astral pearls/turn
Earth Blood Deep Well (Ench 7, Earth 6, cost 80 earth) - "lots" of earth gems/turn
Maelstrom (Evoc 8, Water 6, cost 80 water) - "huge numbers" of water gems/turn
Well Of Misery (Conj 8, Death 6, cost 80 death) - "truckloads" of death gems/turn

... but I can't find anything for nature gems (or blood slaves, natch). Am I missing something?

Also, does anyone know the "huge" numbers for the last three listed? Are they all 20?

TIA,

mother oak alteration 5 10/turn

The last three enchantments give 20 gems per turn.

BTW, why has Nature such a crappy Gem-generating global ? At 50 gems for 5/turn I don't find the deal very interesting : early in the game you'd rather have those 50 gems now, and later the additional +5 isn't that sexy ...

It's 10 per turn, not 5: aren't you thinking of Astral? (5 per turn for 30 gems, which doesn't sound all that great to me)

Damned ! Mothar Oak yields 10/turn ?? Thanks a lot ! I was *sure* it was 5 (as Astral, just more expensive..) and didn't cast it in my recent games due to that !!

Stellar Focus is great, because it's undispelable! It costs 30 gems, gives you 5 right away, and to dispel it it would cost another 30! There's no reason to dispel it, so it's permanent income for you.

[Alneyan]

Stellar Focus can be overwritten by virtually any other enchantment however, unless you feel like putting extra gems when casting it (and quite a few of those too).

The problem with the gem globals is that if you have enough of a particular kind of gem to cast its global, you probably already have a good income of that gem kind. If I have an income of 1 or 2 -- i.e., when a gem-generating spell would help me the most -- the global is much too expensive. Also, most of the gem globals become available at the same time as the other expensive spells I would like to cast. Mother Oak is the exception. Add to these drawbacks the fact that spending the gems for globals does not have guaranteed effects or duration. You could be throwing your gems away, or the global might be cast and then soon replaced or dispelled.

Doesn't Well of Misery have the other good effects too?
