New vote with the better "poll"
1. Disable Forge
2. With disabled Forge Bloodstones are hard to hoard.
So only clams+fetishes need to be balanced.
I would suggest clams cost 20w now and fever fetishes 5n and 20f.
The strange fever fetish cost is because first i planned 10n and 5f as cost but this way machaka could do them very easy but no other nation. This would be unfair but with 5n and 20f machaka has to get lucky also with the random and still needs 1 firebooster. So they would still be an investment but would have a longer paybacktime also.
