Working on my #DnD homebrew fish species based on the #DelversGuideToBeastworld setting after the campaign was in limbo for a whole bit.

I'm adding a body mod system, which I will probably regret, specific to the newly discovered culture.
I will see what the artificer will want to do with the power to get/make magical items that don't take an atunment slot in exchange for a healing mechanic.
The first mod is a magical gill implant that acts like a decanter of endless water, but working at a lower rate without sacrificing an action.
Because the fish species can only breath water, that might be worth the initial risk initially instead if needing a clean tub if water for 1 hour every 24 hours to refill the common water breather item.

The NPC that would even consider that procedure is unintentionally going in the "little mermaid" direction... But I don't think my players would do anything to make her regret it and there are very little people that would...

And I need to figure out what to do with the shark puppy
