🏃‍♀️5e - Underwater🏃‍♀️

A creature that cannot breathe water begins to ☠️suffocate underwater once it cannot hold its breath.

In addition, creatures without swim speeds have DISADV on attacks made using any weapon other than a dagger, dueling dagger, javelin, shortsword, spear, or trident. Ranged weapon attacks automatically miss beyond their normal range underwater, and bludgeoning and fire damage are halved. A creature that takes damage while holding its breath underwater must succeed on a 🎲Concentration Save or immediately begin suffocating as if its breath had run out.
