Wondrous item, very rare (requires attunement by a druid or warlock)

This Tiny pot bears relief scenes of heroes on its cast iron sides. You can use the cauldron as a spell casting focus for your druid spells, and it functions as a suitable component for the Scrying spell. When you finish a long rest, you can use the cauldron to create a Potion of Greater Healing. The potion lasts for 24 hours, then loses its magic if not consumed.

As an action, you can cause the cauldron to grow large enough for a Medium creature to crouch within. You can revert the cauldron to its normal size as an action, harmlessly shunting anything that can't fit inside to the nearest unoccupied space.

If you place the corpse of a humanoid into the cauldron and cover the corpse with 200 pounds of salt (which costs 10 gp) for at least 8 hours, the salt is consumed and the creature returns to life as if by Raise Dead at the next dawn. Once used, this property can't be used again for 7 days.

Whatever form the tool takes, you are proficient with it. While holding this tool, you gain a bonus to the spell attack rolls and the saving throw DCs of your artificer spells. The bonus is determined by the tool’s rarity. As an action, you can focus on the tool to channel your creative forces. Choose a cantrip that you don’t know from any class list. For 8 hours, you can cast that cantrip, and it counts as an artificer cantrip for you. Once this property is used, it can’t be used again until the next dawn.
