Concentration

Concentration is a Common skill, and is modified by your Constutition.

The Concentration skill represents your ability to endure hardship, maintain focus, and push through physical and mental challenges. Whether you’re resisting the effects of pain, staying conscious through exhaustion, or ignoring distractions in a high-stakes situation, Concentration is your go-to skill. It is also used for general checks that require exceptional Constitution.

Anyone can perform the Rejuvinate action, even without ranks in the Concentration skill. However, those who invest in the Concentration skill gain enhanced benefits. For reference, here is the Rejuvinate action:

Rejuvenate: When you take the Rejuvenate action as your Combat Action, you forego all offensive efforts, focusing entirely on restoring your reserves. You regain Mana equal to your Wisdom attribute with a bonus equal to your ranks in the Concentrate skill; Stamina equal to your Endurance attribute with a bonus equal to your ranks in the Survival skill; and Health equal to your Constitution attribute with a bonus equal to your ranks in the Healing skill.

As your skill in Concentration grows, you will gain additional benefits from it.

Initiate (Ranks 10-19):
At this rank, your mental and physical focus begin to solidify into reliable discipline. When maintaining an ongoing spell or effect that requires sustained concentration, you may roll twice and take the better result. This benefit also applies to Magical Feedback checks.

Apprentice (Ranks 20-34):
Secured Mind: When you are targeted by an attack or effect that would Daze, Enthrall, Incapacitate, or Stun you, you can use your Reaction to make a Concentration check. If your check exceeds the Accuracy roll or effect DC, you become immune to the specified conditions from that attack. Other consequences, such as damage or forced movement, are unaffected.

All of these bonuses are cumulative.
