Beast of the Sea: Totally Unusable

[Mork]

"Giant axolotl" is not a thing that had ever occurred to me before, which is genuinely tragic because it means I've wasted years of my life not having them in my fantasy worlds.

giant axolotl mini :D (from reaper miniatures)


When I first read the top post, I was like.. why would a water compagnion work anywhere else except for underwater. It is a specific tool with for a specific situation (underwater campaigns).
But people have made good points that a lot of campaigns are amphibious.. on a boat, in a marsh etc, you want to move in both places..
I think I would rule that the land beast either has a 20ft climb OR swim speed. And if it has a swim speed the penalties of attacking underwater don't apply. The CON modifier # minutes to hold your breath are generous already, so I would just keep that.
