Path of the Tarrasque

Barbarians who walk the Path of the Tarrasque draw their rage from a still-living fragment of a tarrasque that they ingested. Often these fragments are passed down through the barbarian's nomadic tribes or plundered from the sacred burial ground of an ancient warrior.

The fury of the tarrasque courses through the barbarian, transforming them when they rage.

Chitinous Rage

Starting when you choose this path at 3rd level, hard plates protrude from your back while raging. If an attack misses you while raging, you can spend your reaction to reflect the attack, making the attacker the target.

Until rage ends, any time you are targeted by a ranged attack or a spell that requires an attack roll, you can use your reaction to make a DC 15 strength check to be unaffected by the attack and direct it back towards the caster. The caster must make a DC 8+prof+STR dexterity saving throw; on a failed save, the spell is reflected back at the caster as though it originated from you, turning the caster into the target.

Strength Rules All

Beginning at 6th level, if you have to make a saving throw while raging you can make a strength saving throw instead of the required one. You can use this a number of times equal to your proficiency bonus and regain all expended uses after a long rest.

Titanic

Beginning at 10th level, Your hit point maximum increases by an amount equal to level multiplied by your STR modifer when you gain this ability. Whenever you gain a level thereafter, your hit point maximum increases by additional hit points equal to your STR modifier.

Monstrous Strength

Starting at 14th level, while raging your strength increases by 6 even if you are already at maximum strength. (This cannot increase your strength above 30)
