[@obisemkenobi] Pick the traits you're happiest with and put them in your sheet, preferably in the powers or notes section. So if you like for your Atlantean's to have trouble becoming dehydrated upon land then mention it in the sheet. If otherwise, state that too. Personally I think that Atlantean's should become weaker the longer they go without water, but can still survive about three days without. The only exception to that rule would be half breeds like Aquaman.
