Movement buffs attached to credos are actually pretty OP and you are at a huge disadvantage if your opponent has all of the movement credos and you do not.
Fisherman credo:
Increased speed when swimming.
Strider Credo
-Traverse ridges faster (like frikkin 60% faster btw)
-Reduced stamina drain from running in forests (Pretty much everywhere outside of your walls is a forest tile lol. During chases/escapes you drain less energy and drink less often than your opponent (drinking makes you run slower))
Pearl-diver:
-Increased speed when swimming
And in some niche situations, hunter & forager:
-Increased speed when pursuing animals
-Speed bonus when chasing small animals
(Basically chasing rabbits or animals you've sent fleeing in the direction you'd like to go)
This is assuming you're both running on land chasing/fleeing
