Chronozon

Chronozon is a demon that must be defeated towards the end of the Family Crest Quest. It is found in the Wilderness area of the Edgeville Dungeon, by the Earth obelisk. Chronozon must be hit with all four elemental blast spells in order to be killed, or otherwise it will return to full health when it is nearly dead. Players should note that he has to be hit; if the spell splashes, it will not count. It will not drop the crest part unless the player has completed most of the quest. Players do not get any experience from fighting Chronozon.

It is optional but recommended to bring an antipoison before encountering Chronozon, because players will have to pass an area filled with poison spiders to get to it.

Location
Chronozon is located in Edgeville Dungeon in level 2-3 Wilderness, in front of the Earth Obelisk.

Trivia

 * Chronozon is an anagram for Choronzon, a demon or devil that originated in writing with the 16th century occultists Edward Kelley and John Dee within the latter's occult system of Enochian magic.
 * Before a recent update, it was the only demon that always dropped bones instead of ashes.
