Usurp Spiritfont

8th-level necromancy

Casting Time: 1 action
Range: 10 feet
Components: V, S, M (a silver tuning fork worth at least 250 gold, which is consumed by the spell)
Duration: Concentration, up to 1 hour

You exert your will over supernatural phenomena. One spiritfont within range must make an Intensity saving throw. On a failed save, you gain control of the spiritfont. On a successful save, the spiritfont becomes active, if not already, and hostile, attacking you.

When you gain control of a spiritfont, you know its type, Intensity, range, and what actions it can take. For the duration of the spell, you can take a lair action using one of the spiritfont’s actions on initiative count 20, losing any ties. You can also change the state of the spiritfont between dormant and active as a bonus action. If at any time you exit the spiritfont’s range, the spell ends. The spiritfont becomes hostile and attacks you once the spell ends.

You can’t target a spiritwell with this spell.
