Aegir's Ancenstral Ruby

This brilliant ruby is held within a golden brooch that emits the faint sound of distant rain and thunder. Created by the powerful Freya, this ruby is said to contain a sliver of the powerful weapon Mjölnir. When attuned to by a spellcaster the ruby will occasionally flash as though lighting is striking from within the gem.

The brooch has 5 charges. While wearing it, you can use an action to expend 1 or more of its charges to cast one of the following spells from it, using your spell save DC: Feather Fall (1 charge), Warding Wind (2 charges), Call Lightning (3 charges), Fly (4 charges), or Commune with Nature (5 charges). You can also cast these spells using spell slots you have of the appropriate level.

The ruby brooch regains all expended charges after a long rest.
