To keep Shovel permanently in Baldur's Gate 3, follow these steps:

• Find the Scroll of Summon Quasit in the Apothecary's cellar in the Blighted Village (behind a secret passage revealed by a lever near stacked boxes)

• You must have at least one level in Wizard, Warlock, or Sorcerer class to unlock Shovel permanently. If your current class is not one of these, respec to one of these classes temporarily (Wizard is recommended)

• Cast the Scroll of Summon Quasit while playing as a Wizard, Warlock, or Sorcerer. Do not learn the spell directly if you want to keep Shovel after respeccing; instead, cast it from the scroll

• After summoning Shovel, exhaust the dialogue options with her, making sure to keep her name as "Shovel" when prompted. This dialogue unlocks the permanent summoning spell for your character

• Once the spell is unlocked, you can respec back to your original class if desired, and you will still retain the ability to summon Shovel permanently

• Avoid using Storm Sorcery, Wild Magic, or Shadow Magic subclasses when casting the scroll, as these can lock you out of the necessary dialogue to keep Shovel permanently

By following this method, you can keep Shovel as a permanent familiar regardless of your final class choice

. In summary, the key is to temporarily have at least one level in Wizard, Warlock, or Sorcerer, cast the scroll to summon Shovel, complete the dialogue properly, then respec back if you want. This grants you the permanent summoning spell for Shovel for the rest of your run
