Feitan's ability was called Pain Packer.
It used Nen to create a miniature sun that released temperatures high enough to burn living creatures to death within a short time, over a considerable area.

Watching from outside the combat zone, Biscuit and Shizuku both started slightly at Feitan's sudden eruption of aura, shock showing in their beautiful eyes.
The black skull patterns, their features twisting within the aura, already looked remarkably close to post-mortem Nen.
A single glance was enough to tell how
