Hey there,

I'm using the extra origins mod and even though I already changed the health formula to (baseHealth * 0.5) + max(2 * log2(uniqueFoodsEaten), 0) (so giving me only half of the hearts of basehealth), I start with 0.5 hearts when I start with the inchling, instead of 2.5. This might be because spiceoffabric is manipulating the health before extra origins, so spiceoffabric reduces it to 5 hearts, while extra origins then removes 5 hearts afterwards.
Spiceoffabric would therefore have to be "intialized" after origins / extra origins. Though I don't know if that is possible / a bug of this mod

EDIT: This also happens with the origins mod and any of their origin, just because they are hard coding all their health changes.

I could open a pull request on these mods to "fix" this, by using a multiplier (like here) instead of a fixed value.
They would have to change the mod description on the other hand, because technically, they wouldn't start with e.g. 5 hearts less then, but 50% of the health (not making a difference normally, but in combination with this mod e.g. it does.

Alternatively, spiceoffabric would need to fix this by changing the health value after origins, as already stated.

Edit: pr open for extra-origins

It looks like at least Origins is already using modifiers, but they probably come after Spice Of Fabric.
I'm not completely sure how to reliably put SoF behind Origins.
