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.
You can rage 3 times per long rest.
While raging, you gain the following benefits if you aren't wearing heavy armor:
You have advantage on Strength checks and Strength saving throws.
When you make a melee weapon attack using Strength, you gain a +2 bonus to the damage roll.
You have resistance to bludgeoning, piercing, and slashing damage.
If you are able to cast spells, you can't cast them or concentrate on them while raging.
Rage ends early if you are knocked unconscious or if your turn ends and you haven't attacked a hostile creature since your last turn or taken damage since then. You can also end your rage on your turn as a bonus action.
