Path of the Giantslayer

Giantslayer Barbarians focus all of their strength and skill with weapons into powerful strikes meant to cripple the largest of foes. With their size and bulk they can effectively grapple, pin, and submit far larger opponents. They prize themselves on their unique tactics to fight these monsters and their resistance to their attacks, while striking back with equal ferocity.

Enlarge

Starting at 3rd level, you have the ability to grow to an immense size to fight your enemies. You can use a bonus action to gain the following benefits for one minute:

• Your size doubles in all dimensions, and your weight is
  multiplied by eight.
• Your size increases by one category. If you were Small,
  now you are Medium. If you were Medium, now you are
  Large.
• Your weapons also grow to match your new size. While
  these weapons are enlarged, you deal 1d4 extra damage
  when you make melee weapon attacks with them.

Everything you are wearing and carrying changes size with you. Any item dropped returns to normal size at once. If there isn’t enough room for you to double in size, you attain the maximum possible size in the space available. This effect can not be counterspelled or dispelled.

Dominating Presence

Starting at 6th level, you project a threatening presence that makes it difficult for enemies to focus on other targets when you enter your rage. While you’re raging, the first creature you hit with an attack on your turn becomes focused on your actions and movements, which hinders its attacks against other targets. Until the start of your next turn, that target has disadvantage on any attack roll that isn’t against you, and when the target hits a creature other than you with an attack, that creature has resistance to the damage dealt by the attack. The effect on the target ends early if your rage ends.

Titanslayer

Starting at 11th level, you can use a bonus action to consume two uses of Rage, instead of one, to grow even larger than previously possible. You can also use a bonus action to consume an extra use of Rage if you are already Enlarged. While you are in this state, you gain the following benefits in place of the Enlarge feature's benefits:

• Your normal size quadruples in all dimensions, and your
  weight is multiplied by sixty four.
• Your size increases by two categories of your original. If
  you were Small, now you are Large. If you were Medium,
  now you are Huge.
• Your weapons also grow to match your new size. While
  these weapons are Titan-sized, you deal 2d4 extra damage
  when you make melee weapon attacks with them.

 

Earthshaker

Starting at 14th level, you can use your action to slam your boot into the ground, and cast the earthquake spell centered on yourself. When you cast it in this way, the spell does not require your concentration (each creature in the area must still make a Dexterity saving throw at the end of each turn to avoid falling prone) and the spell ends at the end of your next turn. You ignore the difficult terrain created by the spell and you automatically succeed on any Dexterity saving throws you make if a fissure opens beneath you, but you are still subject to any falling structures or other secondary environmental effects caused by the spell. The DC for any saving throws made against this spell is equal to 8 + your proficiency bonus + your Strength modifier. Once you use this feature, you can't use it again until you finish a long rest.
