Ritual Stone

You have attuned to the stars of the Ritual, granting you the following benefits:

You learn the animate dead and speak with dead spells. You can cast these spells without expending a spell slot. Once you cast these spells in this way, you can’t cast them in this way again until you finish a long rest. You can also cast these spells using spell slots you have of the appropriate level. The spells’ ability is your classes or your highest mental stat (Intelligence, Wisdom or Charisma).
