Once per day, use a quick action to start raging. A rage lasts until the end of battle, or about 5 minutes.
While raging, you roll 2d20 to hit with your barbarian melee and thrown weapon attacks instead of 1d20. Use the higher roll for the attack. If you roll a natural 11+ with both dice and your highest attack roll is a hit, the attack is a critical hit!
Recharge 16+: After a battle in which you rage, roll a d20 and add your Constitution modifier. On a 16+, you can use Barbarian Rage again later in the day.
Whenever the escalation die is 4+, as a quick action, you can start raging for free. (It doesn’t count against your normal usage.) This rage lasts until the end of the battle, as normal.
You can now start raging freely when the escalation die is 3+.
You can now start raging freely when the escalation die is 2+.
