When Climbing and Swimming were combined into Athletics, Caiman Swim and Spider Climb were replaced with Athleticism.
Caiman Swim had two additional abilities besides a swimming boost though, that were lost in the combination of spells.

It allowed us to breath underwater (after getting so much skill) and allowed us to stay dry when swimming.
I was wondering if the spell could be reintroduced with just those two abilities, either under the same name or a different one?
