In that they should produce stacks of 10. I’m talking about Derketo’s transmutations or the Ymir’s ice shards to ice.
For example trying to get ice in the desert a stack of 1,000 ice would require 1 thousand human sacrifices which is insane. Same as transmuting vines to aloe. That 1:1 is fine, but it also requires the the sliver of the unfulfilled which means to get 1000 aloe you also need 1 thousand human sacrifices.
I think this one simple fix would go a long way to make those two religions a little more viable.
