Level 2: You gain an uncanny sense of when things aren't as they should be, giving you an edge when you dodge perils. You have Advantage on Dexterity saving throws unless you have the Incapacitated condition.
Level 2: You can throw aside all concern for defense to attack with increased ferocity. When you make your first attack roll on your turn, you can decide to attack recklessly. Doing so gives you Advantage on attack rolls using Strength until the start of your next turn, but attack rolls against you have Advantage during that time.
Level 3: Your Rage taps into the life force of the World Tree. You gain the following benefits.
Vitality Surge. When you activate your Rage, you gain a number of Temporary Hit Points equal to your Barbarian level.
Life-Giving Force. At the start of each of your turns while your Rage is active, you can choose another creature within 10 feet of yourself to gain Temporary Hit Points. To determine the number of Temporary Hit Points, roll a number of d6s equal to your Rage Damage bonus, and add them together. If any of these Temporary Hit Points remain when your Rage ends, they vanish.
Level 3: You gain proficiency in another skill of your choice from the skill list available to Barbarians at level 1.
In addition, while your Rage is active, you can channel primal power when you attempt certain tasks, whenever you make an ability check using one of the following skills, you can make it as a Strength check even if it normally uses a different ability: Acrobatics, Intimidation, Perception, Stealth, or Survival. When you use this ability, your Strength represents primal power coursing through you, honing your agility, bearing, and senses.
Level 5: You can attack twice instead of once whenever you take the Attack action on your turn
Level 6, Whenever a creature you can see starts its turn within 30 feet of you while your Rage is active, you can take a Reaction to summon spectral branches of the World Tree around it. The target must succeed on a Strength saving throw (DC 8 plus your Strength modifier and Proficiency Bonus) or be teleported to an unoccupied space you can see within 5 feet of yourself or in the nearest unoccupied space you can see. After the target teleports, you can reduce its Speed to 0 until the end of the current turn.
Level 7: Your instincts are so honed that you have Advantage on Initiative rolls.
Level 7:As part of the Bonus Action you take to enter your Rage, you can move up to half your Speed.
Level 9: If you use Reckless Attack, you can forgo any Advantage on one Strength-based attack roll of your choice on your turn. The chosen attack roll mustn't have Disadvantage. If the chosen attack roll hits, the target takes an extra 1d10 damage of the same type dealt by the weapon or Unarmed Strike, and you can cause one Brutal Strike effect of your choice. You have the following effect options.
Forceful Blow. The target is pushed 15 feet straight away from you. You can then move up to half your Speed straight toward the target without provoking Opportunity Attacks.
Hamstring Blow. The target's Speed is reduced by 15 feet until the start of your next turn. A target can be affected by only one Hamstring Blow at a time—the most recent one.
Level 1: Unarmored Defense
