You have enhanced the formulas for your mutagens, aligning them perfectly to your physiology. When under the effect of a mutagen you crafted, you do not suffer its drawback.
You push back your rage for a moment in order to think clearly. Until the end of this turn, you can use actions with the concentrate trait even if those actions don’t have the rage trait.
Your fury fills your foes with fear. While you are raging, your Demoralize and Scare to Death actions (from the Intimidation skill and an Intimidation skill feat, respectively) gain the rage trait, allowing you to use them while raging. As soon as you meet the prerequisites for the skill feats Intimidating Glare and Scare to Death, you gain these feats.
Thrown weapons become especially deadly in your fury. You apply the additional damage from Rage to your thrown weapon attacks. If you have the Brutal Critical feat or the devastator class feature, apply their benefits to thrown weapon attacks.
With a quick sprint, you dash up to your foe and swing. Stride twice. If you end your movement within melee reach of at least one enemy, you can make a melee Strike against that enemy. You can use Sudden Charge while Burrowing, Climbing, Flying, or Swimming instead of Striding if you have the corresponding movement type.
Desperate to finish the fight, you pour all your rage into one final blow. Make a Strike. If it hits, you gain a circumstance bonus to damage equal to the number of rounds remaining in your Rage (maximum 10). After this Strike, your Rage immediately ends, and you are fatigued until you rest for at least 10 minutes.
You keep pace with a retreating foe. Stride up to your Speed, following the foe and keeping it in reach throughout its movement until it stops moving or you’ve moved your full Speed. You can use No Escape to Burrow, Climb, Fly, or Swim instead of Stride if you have the corresponding movement type.
You can enter a second rage, but afterward you need to catch your breath. You can Rage without waiting for 1 minute after the previous Rage (or 1 round, with quick rage), but when you end this second Rage, you’re fatigued until you rest for 10 minutes.
