Movement and Attacks in Underwater Combat

In underwater combat, movement and attacks can be influenced by the resistance of the water and other related factors. It’s important to understand the limitations posed by the aquatic environment in order to effectively engage in combat below the surface. According to the Player’s Handbook, certain restrictions apply to creatures without a swimming speed.

Disadvantage in Melee Attacks

Creatures without a swimming speed have disadvantage on melee attacks in underwater combat, unless they make use of specific weapons such as daggers or spears. These weapons are more adept at slicing through the water, enabling more precise strikes against foes. By utilizing these weapons, combatants can mitigate the hindrance caused by the water’s resistance. It’s crucial to choose appropriate weapons to maximize your chances of landing successful melee attacks in underwater combat.

Disadvantage in Ranged Attacks

The resistance of the water also imposes a disadvantage on ranged attacks in underwater combat. Unless using specific ranged weapons like crossbows or nets, combatants face difficulty in accurately hitting their targets. These specialized weapons are designed to overcome the resistance of the water, enabling more effective strikes. When engaging in ranged combat underwater, it’s essential to select the appropriate weapons to overcome the limitations imposed by the aquatic environment.

Holding Your Breath

Unless you have some magical way of breathing underwater you will also have to worry about holding your breath during underwater combat. According to 5e rules the number of minutes you can hold your breath underwater is equal to 1 + your Constitution modifer (minumum 30 seconds).

After you run out of air you can survive a number of rounds equal to your Consitution modifer. After this your character drops to 0 hit points and is drowning. You can not stabilize or heal until you are able to breathe again.

As an example a character with a CON modifier of +3 would be able to hold their breath during underwater combat for 4 minutes. After the 4 minutes the can survive for 3 rounds before they need to start making death saving throws.

As you can see, if you have some magical means of breathing underwater, that is best.
