My brother and I were discussing freminets little air tank and he said that freminet had it because he’s a little dumb and will accidentally swim out of the Fontaine borders and drown so he has it just incase and to help him get back to land or Fontaine.
If you don’t know vision users can breathe underwater without any difficulty due to the blessing of their archon. But this is only for Fontaines waters. Likely it’s just to show he’s a diver by giving him an air tank but truly it’s a bit “useless” when you compare it lore, especially seeing how small it is indicates he doesn’t seem to dive for very long periods of time.
