Path of the Wrestler

Every barbarian needs a way to fuel their rage; some are influenced by powerful natural forces, others prefer to take a more spiritual path. Then there are those others who simply just want to put a Tarrasque in a headlock.

Grappling Techniques

Starting when you choose this path at 3rd level, you don't embrace the power within, you embrace the power outside: your muscles, the greatest weapon you have. While you're raging, you can make an attempt to grapple a creature as a bonus action.

Additionally, you gain proficiency with improvised weapons. The damage of these weapons should be equal to that of a similar weapon. For example, a broken bottle could be compared to a dagger. However, this damage is up to your DM's discretion.

Giant's Strength

At 6th level, when you enter a rage, you can use your action to to cast enlarge on yourself. When casting this spell using this feature, you do not need to concentrate on this spell, and the duration lasts for that of your rage.

Once you use this feature, you can't use it again until you finish a long rest. Beginning at 14th level, you can use this feature once per short rest. At 20th, you can cast it with every rage.

Headlock

At 10th level, while you are raging under the effects of an enlarge spell cast using your Giant's Strength feature, you can attempt to put one creature you are grappling into a headlock.

On your turn you can forgo one of your attacks to make another grapple check against your grappled target. If you succeed on the second check, the target is restrained until the start of your next turn. You can continue to make this check on each of your turns.

Relentless Grapple

Beginning at 14th level, when a creature fails to break out of your grapple, you can use your reaction to make one waepon attack against the creature.
