Rage Stacking

Prerequisite: Barbarian Class

You have learned to push your Rage beyond the natural limits of your body, channeling increasingly destructive power at the cost of your physical endurance, mental stability, and ultimately your own life.

Rage Stacking

While Raging, you can use a Bonus Action to increase your Rage Stack by 1, up to a maximum of 7 stacks.

Each stack grants cumulative benefits according to the table below. Bonus Rage Damage is added to the damage of attacks that qualify for your normal Barbarian Rage damage bonus.

You cannot activate Rage Stacking while you have one or more levels of Exhaustion.

If you gain Exhaustion while Rage Stacking is active, your Rage Stacks immediately reset to 0, and you suffer the backlash associated with the highest stack reached.

Rage Stack Progression

All bonuses are cumulative. Backlash damage and Exhaustion are determined by the highest Rage Stack reached, not the sum of previous stacks.

Reckless Fury

While you have at least one Rage Stack, you must use Reckless Attack whenever you are eligible to do so.

Loss of Control

At the start of each of your turns while Rage Stacking is active, you must make a Wisdom saving throw.

The saving throw DC equals 10 + your current Rage Stack.

On a failed save, you lose control of your aggression and must attack the nearest creature, whether friend or foe, during that turn.

Mental Strain

Beginning at Rage Stack 2, you have Disadvantage on Intelligence and Wisdom saving throws, including saving throws against Loss of Control.

Physical Strain

Beginning at Rage Stack 3, you take Force damage equal to your current Rage Stack at the start of each of your turns.

This damage cannot be reduced or prevented.

Backlash

When your Rage ends, you immediately suffer Force damage and gain levels of Exhaustion according to the highest Rage Stack reached during that Rage.

Backlash damage cannot be reduced or prevented by resistance, immunity, or other effects.

Exhaustion gained from Backlash is added to any existing Exhaustion. Reaching Exhaustion Level 6 results in death.

Backlash occurs only once per Rage, regardless of how many stacks were accumulated.

Seventh Stack — Death's Threshold

Upon reaching the seventh Rage Stack, you surpass the absolute limits of your mortal body. Your muscles tear, your bones fracture, and your life force burns uncontrollably as your Rage reaches its ultimate form.

Final Stand. During your next turn after reaching the seventh stack, every attack you make that successfully hits is considered a Critical Hit, regardless of the attack roll. Damage dealt by these attacks ignores damage resistance, but not immunity.

The Seventh Sin: Wrath Incarnate. At the end of that turn, your body violently explodes, releasing a catastrophic wave of destructive energy in a 30-foot-radius sphere centered on you.

Every other creature within the radius must make a Dexterity saving throw against a DC equal to:

8 + your Proficiency Bonus + your Strength modifier + your Barbarian level.

On a failed save, a creature takes 25d6 Force damage, or half as much damage on a successful save.

Your body is reduced to ash, and you die instantly, regardless of your remaining Hit Points. You do not fall Unconscious or make Death Saving Throws.

Once the seventh stack is reached, your death is inevitable. Ending your Rage, receiving healing, or reducing your Rage Stacks cannot prevent it.

Beyond Mortal Restoration. A creature killed by Death's Threshold cannot be returned to life through Revivify, Raise Dead, Reincarnate, Resurrection, or similar magic.

Only True Resurrection, Wish, or direct intervention from a deity or comparable cosmic power can restore the creature to life.

The Seventh Sin: Wrath Incarnate is a special Barbarian ability, not spellcasting. It requires no spell slot, cannot be Counterspelled, and can activate while Raging. It cannot be activated independently of Rage Stacking.
