Deathfire Monk

"These monks like their prey cooked before they feed, so they will blast you with fireballs." A Deathfire Monk is an enemy found in Rise of the Triad, not making an appearance until the fourth episode.

Strategy
His fireballs are deadly, but they can be used against him. He can hurt himself if he hits a wall that's close to him. Although he won't start his attack if enemies are in the way, you can still make him do it by running into his line of fire, then getting behind an enemy. This can be used to more quickly get through the hordes of monks, who can be time consuming to kill because of their huge HP.
