Demon executioner

Demon executioners are level 82 Summoning familiars. They belong to the Demon group of familiars, and currently share the special move, Ring of fire, with two other demons: demon deacons and demon brawlers. This group of familiars also share the unique trait of being aggressive; they will automatically engage in combat with new enemies of the same type as the ones you are currently attacking (Though you must be in combat for their aggression to activate).

Ring of fire scroll
The Ring of fire scroll enables the Ring of fire special move for a Demon executioner. Using the pouch on a summoning obelisk creates 10 scrolls.

Ring of fire
Ring of fire is the special move for the demon class of familiars, which is a magic based area of effect attack that hits all monsters within 4 tiles of the familiar.

Trivia

 * When in a God Wars Dungeon encampment, this familiar will treat non-slayer creatures as the same type of enemy, thus engaging any of them in combat automatically. If you attack a slayer creature (i.e. spiritual mage), however, they will begin to attack that class of monster too.
