The Reign of Darkness
Ring of Combustion
This dark ring appears crafted of wood so badly burned that it resembles little more than charcoal. Ash and charred wood crumble away from the ring when it is handled, though its durability is ultimately unaffected.
When initially worn, the ring begins to heat up (as if a metal object under the effect of a heat metal spell) as it attunes to the wearer. If the wearer keeps the ring on for the entire 7 round duration, it attunes to him and can be activated at will.
When activated, the ring generates the heat and flame of a campfire as needed for spells such as pyrotechnics and other abilities such as fire supremacy.
Additionally, the ring can cast spark on command.
