Johnathon Fitzharmon is the brother of Caleb and Avan and one of the sons of Dimintheis. He can be found on the 1st floor[UK]2nd floor[US] of the Jolly Boar Inn. Johnathon plays a role in the Family Crest quest: he was fighting Chronozon, a powerful demon in the Edgeville Dungeon, but began losing the fight and tried to retreat. In his way was a poison spider, which bit him, poisoning him. When the player meets him, he will ask for an antipoison to cure himself.
After the player brings him an antipoison, he tells the player that in order to beat Chronozon, the player must cast all four blast spells at least once. After the quest is complete, he offers to enchant the steel gauntlets into chaos gauntlets, which increase the maximum damage of all bolt spells by 3. If the gauntlets are already imbued with another power, Johnathon will ask for 25,000 coins to re-enchant them.
