Tank Top Master

Tank top masters are fighters who have devoted themselves to the discipline of tank top "magic": a system of training, conditioning, and style stemming from the tank top, a simple form-fitting top made from cotton with a low neckline and no sleeves. Melee-oriented and focused on building muscular and athletic physiques, tank top masters have a dedication and resilience that belies their casual styles. Despite not wearing traditional armor they can "tank" powerful hits, taking as good as they get and inspiring their allies to join the fight as they bludgeon down foes. Looked down on by many warriors, tank top masters are still a tradition unafraid to confront the evils of the world, willing to adventure far and wide for the common folk of their communities and kingdoms and protect them from horrors both mundane and cosmic.

Level 3: Tank Top Magic

Through sheer willpower, grueling training and belief in the tank top, fighters of this archetype flex a superior speed and defense that is almost certainly at least a little bit supernatural.

You have a Strength modifier bonus to your unarmored AC, and +5 unarmored movement speed.

Level 3: Remarkable Physique

Paying great attention to detail in their diets and training regimen, tank top masters unlock a whole new level of mass and muscle that makes the fit of their tops pop.

You have +1 bonus HP per level, and count as one size larger when determining your Push, Drag, and Lift weights.

Level 7: Melee Bruiser

Walking into melee combat unarmored requires a special type of bravery, which tank top masters possess in addition to extensive training with their fists and other melee weapons and an arsenal of suplexes and submission holds.

You gain an unarmed strike that deals 1d4 Bludgeoning damage, the Grappler feat, and +2 bonus damage on melee weapon attacks.

Level 10: Tank Top Justice

With a sense of justice enhanced by their tight-fitting tank top, tank top masters strike back against all manner of hooligans and their bogus hijinks with a surge of adrenaline and aggression that inspires nearby allies to press towards victory.

During combat, immediately after a creature within 5 feet of you hits you with a melee attack, you can make an Opportunity Attack against that creature; if the attack hits, you can give Heroic Inspiration to yourself or an ally within 30 that can see and hear that lacks it.

Level 15: Determination

The simplicity of the tank tops style is translated to purity of purpose in the philosophy of this archetype, with determination to grind out one more rep of justice and leave the gym of the world just a little better than it was yesterday. Tank top magic amplifies this into an irrepressible conviction that can bounce back from almost anything.

You gain the Resistance cantrip but can only cast it on yourself, with the die being 1d6; this uses a bonus action and doesn't require your concentration. You can only benefit from one instance of the Resistance cantrip at a time; you choose which one. You can use this trait proficiency bonus times a Long Rest. 

Additionally, you cannot be Grappled and can stand up from Prone with only 5 feet of movement.

Level 18: Tank Top Resilience

With unbridled hustle, and loyalty and respect for the tank top, your Tank Top Magic reaches the pinnacle of resilience in battle, giving you these two benefits.

Death Defying Fit. You have Advantage on Death Saving Throws. Moreover, when you roll 18–20 on a Death Saving Throw, you gain the benefit of rolling a 20 on it.

Tank Top Rally. At the start of each of your turns, you regain Hit Points equal to 5 plus your Strength modifier if you are Bloodied and have at least 1 Hit Point.
