Mosswbody vs protection

[Squirrelloid]

there are two types of protection: natural protection and manufactured protection. These add non-linearly, such that as total protection increases, the impact of raising the lesser contributor is decreased. At low protection totals (<15) it should look pretty linear.

Barkskin similarly adds an amount to natural protection based on existing natural protection. This is +10 at low levels of natural protection, and decreases as natural protection increases.
