Trivia

 * Cursed Inferno may have been inspired by Wildfire from A Song of Ice and Fire / Game of Thrones as both are flames that can't be extinguished by water and are also colored green, which in turn was based upon Greek fire, an incendiary weapon created by the Byzantine Empire.
 * It may also have been a reference to the green flame - one of the Burning Legion's visiting cards from the Warcraft franschise.
 * There is no way to prevent or counter the Cursed Inferno debuff.
