Sealed Dragon: Barbarian

Scales

Your rage is so great that at 1st level your beautiful scales already have an effect. While not wearing armour, your AC is 10 + Dexterity Modifier + Constitution Modifier.

At 18th level, you gain damage resistance to elemental damage aligned with your ancestry.

Reckless Attack

Starting at 2nd level, you can throw aside all concern for defense to attack with fierce abandon. When you make your first attack on your turn, you can decide to attack recklessly. Doing so gives you advantage on melee weapon attack rolls using Strength during this turn, but attack rolls against you have advantage until your next turn.

Draconic Intuition

At 2nd level, you awaken your uncanny sense of knowing when things nearby aren’t as they should be, giving you an edge when you dodge away from danger.

You have advantage on Dexterity saving throws against effects that you can see, such as traps and spells. To gain this benefit, you can’t be Blinded, Deafened, or Incapacitated.

The Seals Start to Fracture

At 3rd level, the tiniest cracks have begun to form in your Seals.

You can imbue your draconic might to go into a frenzy when you rage. If you do so, for the duration of your rage you can make a single melee weapon attack as a bonus action on each of your turns after this one. When your rage ends, you suffer one level of exhaustion.

Ability Score Improvement

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.

Using the optional feats rule, you can forgo taking this feature to take a feat of your choice instead.

Extra Attack

Beginning at 5th level, you can attack twice, instead of once, whenever you take the Attack action on your turn.

Fast Movement

Starting at 5th level, your speed increases by 10 feet while you aren’t wearing heavy armor.

Breath Weapon

The Seals on you start breaking. At 6th level, you can finally access your fundamentum and exhale destruction that defines a Dragon. Once per short or long rest you exhale a breath aligned with your ancestry as shown in the Dragon racial table. The damage die is d6, the number of dice is half your level (rounded down), and the save DC is your spell save DC. On a successful save, targets take half damage.

At 9th level, this breath can also recharge on a 20 on a d20, at 14th level, it recharges on 18 or above on a d20, and at 19th level, it recharges on 15 or above on a d20.

Draconic Instinct

By 7th level, your instincts are so honed that you have advantage on initiative rolls.

Additionally, if you are surprised at the beginning of combat and aren’t Incapacitated, you can act normally on your first turn, but only if you enter your rage before doing anything else on that turn.

Brutal Critical

Beginning at 9th level, you can roll one additional weapon damage die when determining the extra damage for a critical hit with a melee attack.

This increases to two additional dice at 13th level and three additional dice at 17th level.

Claws

At 10th level, the Seals deteriorate further and you are now able to manifest your claws. They are considered Finesse weapons, and deal 2d6 damage on hit. They are not considered magical weapons for the sake of overcoming immunity or resistance.

Relentless Rage

Starting at 11th level, your rage can keep you fighting despite grievous wounds. If you drop to 0 hit points while you’re raging and don’t die outright, you can make a DC 10 Constitution saving throw. If you succeed, you drop to 1 hit point instead. Each time you use this feature after the first, the DC increases by 5. When you finish a short or long rest, the DC resets to 10.

Wings

The Seals deteriorate further and allow you to unfurl your wings again. At 14th level, once per long rest, you are able to manifest your wings as a bonus action. These wings last 5 hours or till you dismiss them as a bonus action. To do so, you must be wearing light armour, or no armour. If you don any other armour while your wings are present, you take 5d6 bludgeoning damage every 12 seconds. If you are reduced to 0 HP by this damage, you cannot use your wings to fly till they are healed by a Heal spell or a Regeneration spell.

With your wings, you have a flying speed of 30 feet.

At 18th level, your flying speed increases to 60 feet.

Persistent Rage

Beginning at 15th level, your rage is so fierce that it ends early only if you fall unconscious or if you choose to end it.

Indomitable Might

Beginning at 18th level, if your total for a Strength check is less than your Strength score, you can use that score in place of the total.

The Seals Break: Barbaric Might

Broken and destroyed, your seals are finally gone but you have not lost the experience and power you have gained as a mortal, adding to your already supreme true form. But despite this, there are lingering embers that burn from your seals and you cannot maintain your true form permanently ..... yet. Maybe one day, you will find the ability to permanently remove your seal.

At level 20, you can finally assume your true form. You shapeshift into an ancient Dragon equivalent of your draconic species as an action. You can’t use this ability again until you finish a long rest. You can stay in your Dragon form for 1d4 + 1 hours. You cannot extend or increase your time as your true form in any way.

While in your true form, the following limitations apply:

• When you transform, you assume half the Dragon’s hit points and Hit Dice. When you revert to your sealed form, you return to the number of hit points you had before you transformed. However, if you revert as a result of dropping to 0 hit points, any excess damage carries over to your sealed form. For example, if you take 10 damage in your true form and have only 1 hit point left, you revert and take 9 damage in your sealed form. As long as the excess damage doesn't reduce your sealed form to 0 hit points, you are not knocked unconscious.
• Your breath weapon does 15d10 damage, instead of the damage indicated on the stat block.
• If possible, your equipment drops to the floor. Worn items that are not magical (mundane armour, clothes) are destroyed during the transformation process. Any magical items on you (including worn) drops safely.

Your sealed form statistics are replaced by the statistics of the Dragon if they are higher (capped to 20) but you retain your alignment, personality, Intelligence, Wisdom, Charisma scores, and your HP while in sealed form. You also retain all of your skills and saving throw proficiencies. In addition, you become proficient in Strength, Dexterity, and Constitution saving throws if the Dragon is. If the Dragon has any legendary or lair actions, you cannot use them. You also do not gain legendary resistances.
