Paradisial Flare is a transcendental skill in the form of flames adorned with the paradise of the afterlife. They reverberate a beautiful pink and one feels no heat near them, only upon direct contact.
The damage taken from this transcendental is proportional to the number of intentionally killed humans. That is why most nastikas try to avoid Agni. Gods with the fire attribute other than Agni do not have enough power to threaten a nastika.
