Tempest Staff (Patreon)

Staff, uncommon (requires attunement by a cleric, druid, sorcerer, or wizard)

This staff is made from a branch from a tree that's been struck by lightning. The staff has 3 charges and regains 1d3 expended charges daily at dawn. While holding the staff, you can use an action to expend 1 of its charges to summon a bolt of lightning from the air above a point that you can see within 120 feet of you. Each creature within 5 feet of that point must make a Dexterity saving throw against your spell save DC. A creature takes 4d6 lightning damage on a failed save, or half as much damage on a successful one. There must be at least 20 feet of space above the point for the bolt to appear. If there isn't enough space to accommodate the bolt, the action is wasted, but the charge is not expended.

If you are outdoors in stormy conditions when you use this staff, the lightning damage increases by 1d6.

The crash of lightning can still be felt in its branches. The shuddering of its might remains, and it serves my beck and call.
