Is that a core?

The black, gray and white mist rolled towards the battlefield and Adrian's Nether Gauge was instantly full. Whenever Adrian summons the Nether Domain, he can empower his attacks using 100 nether energy for a duration of 20 seconds. He was basically empowered whenever he summons his Nether Domain.

[All your skills will deal 50% more damage for the duration of Nether Domain.]

[Your stats have been doubled for the duration of Nether Domain.]

[The Calcite Rock Dragon has been affected by Paranoia. All its skill shots have a 50% chance to miss.]

The raid party members could see inside the mist but they did not have the status boosting effects that Adrian is given. The Calcite Rock Dragon felt a weird sensation that it has not felt in all of its life being alive. The rock dragon felt like death was just beside it. It felt that death was claiming its soul to drag to the underworld.
