Mariner

You have spent time at sea and learned to use the tools of a mariner in combat. You gain the following benefits:

You have a swimming speed equal to your base walking speed.

When a creature provokes an opportunity attack from you, you can use your reaction to make a ranged weapon attack against that creature with a net.

When you make a ranged attack with a net, you do not have disadvantage for being within 5 feet of a hostile creature or creatures.

When you wield a trident with one hand, its damage die changes to 1d8 from 1d6. When you wield a trident with two hands, its damage die changes to 1d10 from 1d8.

Tridents count as having the reach property for you.
