Spellcasting focus. Requires attunement by a spellcaster.

A fist sized glassy red gemstone that has a glowing ember in the center. The stone emits an aura of warm air in a 10-foot radius around itself.

The stone must be held in both hands for 1 hour while it vibrates and produces sparks as you struggle to keep hold of it. At the end of the duration you must make a DC 20 Strength saving throw.

On a failed save the stone bursts into flames, causing you to take 8d6 fire damage. If you fail to attune you cannot attempt to do so again until you have finished a long rest. On a successful save you attune to the stone. While attuned to the stone you gain the following features.

Weavesense

You sense the direction and distance to the stone at all times. This effect ends if another creature attunes to it.

Cinder Magic

You gain knowledge of Cinder spells which you can cast with your available spell slots. The stone must be held in the hand to cast these spells.

Flameguard

You are immune to fire damage and resistant to cold damage while the stone is in your possession.

Firestarter

As an action while holding the stone you can touch it against a flammable object that is medium or smaller, causing it to instantaneously ignite.
