Do my NPC's need Amphibian Suits to enter Ocean squares?

Are terrain restrictions in effect for NPC's?

I believe terrain restrictions are in effect for NPCs, but not if they're in your party. For example, I was not able to command a K-4 Security Droid to exit my ship onto mountain terrain, but I was able to add it to my party, exit the ship with it and then kick it from my party so it stood on mountain terrain.

Currently you only need your pc equipped with an amphibian backpack in order to enter ocean squares. Your party does not need any amphibian items.

But if you plan on deploying individual scout NPCs that are not in your party, they will all need to be equipped with backpacks as well.
