You can enter a Rage as a Bonus Action. While raging, you have Resistance to Bludgeoning, Piercing, and Slashing damage, advantage on Strength checks and Strength saving throws, and a bonus to Strength-based damage rolls. Your Rage lasts up to 10 minutes, ending early if you stop attacking or taking damage unless you use a Bonus Action to extend it. You can Rage 4 times per Long Rest, and your Rage Damage bonus is +3.

When damaged by a creature within 5 feet, use a Reaction to make one melee attack against it.

After making an advantaged Strength-based attack, give up the advantage on one attack to deal an extra 1d10 damage and use one Brutal Strike effect.

While not wearing armor, your base Armor Class equals 10 + your Dexterity modifier + your Constitution modifier. Lagertha uses this calculation for an AC of 14, but her current recorded AC is 12 because she commonly fights in minimal clothing and carries her shield in a way that leaves her unprotected when not actively using it.

You can use the mastery properties of four weapons with which you have proficiency. Lagertha has mastered the Greataxe, Handaxe, Javelin, and Maul.

You have advantage on Dexterity saving throws unless you are Incapacitated.

When you make the first attack roll on your turn, you can attack Recklessly. Until the start of your next turn, you have advantage on Strength-based attack rolls, but attack rolls against you also have advantage.

Lagertha follows the Path of the Berserker, channeling her Rage into overwhelming violence.

You gain an additional skill proficiency from the Barbarian's Primal Knowledge options. Lagertha gains proficiency in Perception. While raging, you can use Strength for certain skill checks that normally use another ability, as allowed by the feature.

You gain the Tough origin feat, increasing your hit point maximum by 2 for every character level. This feat is represented in Lagertha's hit point total.

Your Speed increases by 10 feet while you aren't wearing Heavy armor.

While your Rage is active, you are immune to the Charmed and Frightened conditions. If either condition is affecting you when you enter your Rage, it ends on you.

You gain the Alert origin feat. You add your Proficiency Bonus to Initiative rolls, and immediately after Initiative is rolled you can swap your Initiative with a willing ally who is not Incapacitated.
