Clam of Pearls overpowered - manual means 1 pearl each season not each turn

[calmon]

I find clams are overpowered. I don't understand the manual text:

"The entchanted shell produces one pearl of Astral essence each season"

I think this means 1 in spring, summer, autumn and winter. So you should get 1 pearl all 3 turns and not every turn!

Most of gem income is based on the clams and every nation tend to procude them in masses. The gem increasing global entchantments or even magical sites aren't that important. With a good astral income you can do all what you want, the exchange rate in any other gem is only 2:1 (better with alchemist stone) and you can even wish for gems (25 of each sort = 175 gems for only 100 pearls). Astral magic is good enough itself but with the clams (and wish) its a must for most of the nations pretender.

I think the curent clams should be changed to 1 gem all 3 turns. Then other income mechanism increases in value and the game is more richly colored.
