You strive to recreate the might and power of the Maelstrom, the maximum manifestation of the Ocean's fury. You learn to fight like a damaging whirlpool, pulling your enemies closed before crushing them with your enormous weapons.

Fighting Style

Starting at 3rd level, you choose one of the following Fighting Styles:

Great Weapon Fighting: When you roll a 1 or 2 on a damage die for an attack you make with a melee weapon that you are wielding with two hands, you can reroll the die and must use the new roll, even if the new roll is a 1 or a 2. The weapon must have the two-handed or versatile property for you to gain this benefit.

Two-weapon Fighting: When you engage in two-weapon fighting, you can add your ability modifier to the damage of the second attack.

Crashing Currents

Starting at 3rd level, as one of your attacks when using the Attack action when you rage and are wielding a melee weapon in each hand, you can perform a single attack using both your weapons. You make a single Attack roll, and if you hit, you damage is equal to both weapons damage dice+your STR modifier (once). You can still use your off-hand weapon attack as a Bonus action when using this feature.
Alternatively, when wielding only one two-handed weapon, you can use this feature to roll one additional weapon damage die and add it to the damage you deal.
You can use this feature only once per turn, and a number of times equal to your STR modifier each long rest.

Crushing Pull

Starting at 6th level, as a bonus action on your turn, you call upon the natural forces of the Maelstrom to pull any creature within 10 feet of you 5 feet towards you. The target can make a STR saving throw to negate this movement, with a DC equal to 8+your CON modifier+your Proficiency bonus. This movement can provoke attacks of opportunity.
You can use this feature a number of times equal to your CON modifier each long rest.

Ocean Grip

Starting at 10th level, while you are raging, you can use one melee weapon with the Heavy quality in each hand. Should you have access to the Great Weapon Fighting Style, you retain the benefit even when using heavy weapons with one hand.
Additionally, you gain the Fighting style you did not chose as the level 3 feature of this subclass.

Great Weapon Fighting: When you roll a 1 or 2 on a damage die for an attack you make with a melee weapon that you are wielding with two hands, you can reroll the die and must use the new roll, even if the new roll is a 1 or a 2. The weapon must have the two-handed or versatile property for you to gain this benefit.

Two-weapon Fighting: When you engage in two-weapon fighting, you can add your ability modifier to the damage of the second attack.

Maelstrom

Starting at 14th level, as an action in your turn while you are raging and using two melee weapons with the Heavy quality in each hand, you can unleash the power of the Maelstrom.
All creatures within 5 feet of you need to make a DEX saving throw against a DC of 8+your STR modifier+your Proficiency bonus. On a failed save, they will suffer damage equal to both weapon damage dice+double your STR modifier, or half as much on a successful save.
This attack does not allow you to perform your off-hand attack with your Bonus action.
You can use this feature once each long rest.
