They had more magic attacks than most minions and are usually seen using those more than melee. Their abilities consisted of energy shields that they could also use on other minions that blocked all magic and mana abilities such as Dante's Cross and bolts of electricity that could be shot from their staff. They are sometimes accompanied by similar foes known as Pagans.
Because of their power to make the other surrounding enemies immune to Dante's holy attacks, Heretics should be the player's first priority. They are immune to the Cross. Scythe attacks or Magic must be used to defeat them.
- Heretics and Pagans are capable of speech, often invoking the names of lesser beings that they worshipped.
