Waterproof is an explorer and companion perk that reduces the sanity-cost of travel through Shallow River terrain from 4 to 1. The perk also reduces the movement cost in Swamp terrain as well, even though this is not stated in the perk's description.
Explorers can obtain this perk as a random reward option for completing an expedition. Only lizard companions - Lizard Shamans and Warriors come automatically with this perk.
Tips[]
- This perk is most useful in Prehistoric or Jungle worlds, where shallow river and swamp terrain is much more prevalent.
