You can cast Speak with Dead without a spell slot. Charisma is your spellcasting ability for this spell. When you cast the spell in this way, the corpse gains enough of a semblance of life to move and dance with you for the duration of the spell, if it is able. The corpse will generally move where you ask it to, but can't take actions or deal damage. You can also take a Bonus Action to change the target of the spell to a different corpse within range. You can ask a total of five questions, no matter how many corpses you target.
Once you use this feature, you can't use it again until you finish a Short or Long Rest. You can also restore your use of it by expending a use of your ValdaSpire24Extras (no action required).
