Unarmored Defense[edit]

Starting at 1st level, while you are not wearing any armor, your Armor Class equals 10 + your Strength Modifier + your Constitution Modifier. You can use a shield and still gain this benefit.

Stone Arm Weapons[edit]

At 2nd level, you learn how to harden your arms and turn them into weapons. As a bonus action, you may turn your arms into either blades to deal slashing damage or solid stone fists to deal bludgeoning damage. These attacks each deal 1d8 + your Strength modifier of their respective damage types.


At 3rd level, you chose a Cut. Choose between Defender or Excavator, both detailed at the end of the class description. Your choice grants you features at 3rd and again at 9th, 11th, and 14th.

Ability Score Increase[edit]

When you reach 4th level, and again at 8th, 12th, 16th and 19th level, you can increase one ability score of your choice by 2, or you can increase two ability scores of your choice by 1. As normal, you can't increase an ability score above 20 using this feature.


At 5th level, you can completely harden your body to reduce the damage of incoming attacks. Twice per day as a reaction, you may harden your skin to be like stone, reducing the damage of any physical non-magical attack to half damage. You recover your uses of this feature after a long rest. The uses of this feature increase at 11th, 15th, 17th, and 19th.

Stone-Like Resistance[edit]

At 6th level, you gain resistance to fire damage and force damage. Your Hardening feature does not stack with this ability.

Stone Arm Improvement[edit]

At 7th level, your stone arm weapons improve. Your stone arm blades now deal an extra 1d6 of damage and criticals with your stone fists also knock your target prone.


At 10th level, you can reroll a saving throw that you fail. If you do so, you must use the new roll, and you can't use this feature again until you finish a long rest.

Red Riot Counter[edit]

At 13th level, when you use hardening as a reaction, you may also make a counter attack against the attacker with a weapon or your stone arms.

Red Riot Unbreakable[edit]

At 15th level, you make your skin completely impenetrable. Once per day as an action, you harden your entire body for 30 seconds (5 turns), giving your body Total cover, meaning you can't be directly targeted by spells or attacks. You recover your use of this feature after a long rest.

Just Standing Up is Enough[edit]

At 17th level, your resilience becomes outstanding. Once per day, should you be reduced to 0 hp, but not be killed in the process, you may call upon a burst of energy to recover yourself. This burst recovers 3d12 + your Hardening level and you gain 1 level of exhaustion. You recover your use of this feature after a long rest.

Red Riot Unstoppable[edit]

At 18th level, while in your Red Riot Unbreakable form, your stone arm attacks become more powerful. Your arm blades do 3d8 + your strength modifier and your stone fists knock enemies 10 feet back and prone while in Red Riot Unbreakable.

Sturdy Hero: Red Riot[edit]

At 20th level, you've mastered your quirk and have reached the peak of your abilities. Your Strength and Constitution scores are increased by 4. Your maximum for these scores is now 24.


A subclass built around supporting your allies and increasing your defensive abilities.

Front Horse

At 3rd level, you are considered a size class larger for the purposes of your carrying capacity and the weight you can push, drag, or lift. In addition, you gain proficiency in the athletics skill or expertise in the skill if you had proficiency already.

Red Riot Encouragement

At 9th level, your words inspire greatness in others. Twice per day, you may give inspiration to your allies, adding 1d6 to their next roll. You recover your uses of this feature after a long rest.

Shielding the Innocent

At 11th level, twice per day if a friendly creature is within 10 feet of you, you may use your reaction to protect them from damage, taking it in their stead. As a bonus, you have resistance against the attack. You recover your uses of this feature after a long rest.

Stone Fortification

At 14th level, you may add 2 times your Hardening level to your health. For levels after this, you may simply add an additional 2 health per level.


A subclass focused on increasing your offensive capabilities.


At 3rd level, you gain proficiency in intimidation or expertise if you already had proficiency.

Extra Attack

At 9th level, you can attack twice, instead of once, whenever you take the attack action on your turn.

Like a Bulldozer

At 11th level, twice per day, you can bulldoze through A.O.E attacks, such as a red dragon's fire breath or a storm of arrows. During bulldozing, your movement speed is reduced by half during the attack, however the creature making the attack must make a check against your AC. On a failure, you take no damage, but on a success you take half the damage of the attack. Should you reach the creature before they finish their A.O.E attack, you may make an unarmed strike and stop the attack. A creature of a size class equal to or less than your own hit by this attack is stunned for 1d4 turns.

Red Gauntlet

At 14th level, you can harden your arm to break through stone. Your stone fists attacks now deal 2d8 damage+your strength modifier and can also punch through up to 7 inches of stone.
