A storm shard is set at the top of a palm tree wood staff, and inside of the shard a small thunderstorm is visible. The staff is related to the Staff of Thunder and Lightning, but is made by a different process, leaving the storm shard intact instead of displaced throughout the wood. This makes the staff more suited to magic use, but less powerful as a weapon.

This staff used to be a simple +1 magic quarterstaff and it grants a +1 bonus to attack and damage rolls made with it.. While you hold it, you gain a +1 to spell attack rolls. This staff is also an arcane focus.

This staff has 10 charges and regains 1d6 + 4 expended charges daily at dawn. If you expend the last charge, roll a d20. On a 1, the staff cracks in half, letting out a large boom of thunder and dealing 2d6 thunder damage to each creature within 10 feet. 

Power Conduit. You can use your reaction gain resistance to lightning damage until the start of your next turn. When you take lightning damage with this resistance, the staff gains 1 charge. For every 5 points of damage you prevent, the staff gains an additional charge. If lightning damage cases the staff to go above it's maximum charges, roll a d20 to see if the staff gets destroyed as if it had expended its last charge.

Spells. While holding the staff, you can use an action to expend some of its charges to cast one of the following spells from it, using your spell save DC: fog cloud (1 charge), gust of wind (2 charges), call lightning (4th-level version, 4 charges), thunderwave (5th-level version, 5 charges) or control weather (8 charges).

You can also use an action to cast one of the following spells from the staff without using any charges: gust, shape water, or water walk

Minor Storm. While holding the staff, you can use an action and expend 2 charges to cause a storm cloud to spread out in a 60-foot radius from you. The storm lasts for 1 minute, making the area lightly obscured for creatures other than you. When any hostile creature enters the area for the first time on a turn or starts its turn there take 1d6 lightning damage. The storm moves with you, remaining centered on you. A wind of at least 12 miles per hour disperses the storm and ends the effect. This part of effect does not extend underwater.

This feature also causes all water in the same 60-foot radius around you to be difficult terrain for all hostile creatures, except at depths greater than 20 feet. When you use the spell water walk while the storm is active, the waves shape themselves around people affected by the spell.
