Mark of the Inquisitor

Inquisitor Technique: 3rd, 11th, and 17th level When the target of your Ranger's Quarry feature is within 15 feet of you, you gain the following benefits:

• Whenever the creature casts a force power, it must first succeed on a Constitution saving throw against your tech save DC to maintain concentration. On a failed save, the casting is disrupted, the force power fails, and the force points are wasted.
• Whenever the creature starts its turn while concentrating on a force power, it must make a Constitution saving throw against your tech save DC to maintain concentration. On a failed save, it loses concentration on the power.

The radius of this feature increases to 30 feet at 11th level and 60 feet at 17th level.

Granted by Inquisitor Technique at 3rd level.
