Fragment of the Firelord

This small red gem is all that remains of Kossuth, God of Fire.
You may make a DC 15 Religion check. On a success you may cast one of the following spells: Greater Restoration, Wall of Fire, or Haste. On a failure you cast Flamestrike centered on yourself and the gem loses its power for 8 hours.
This ability can only be used once every 3 days.
