Weapon (spear), rare
This crude spear is made entirely of glass forged from lightning striking the earth. A part of the lightning still remains within the glass; the spear emits dim light out to a range of 10 feet while it's held. A target hit with the spear takes an extra 1d6 lightning damage from the attack.
Summon Lightning. If you are holding the spear while the sky is visible and unobstructed above you, you can use an action to speak the spear's command word to cause a bolt of lightning to crash down from the sky and hit a point that you can see within 30 feet of you. Each creature within 20 feet of the point, other than you, must then make a DC 15 Dexterity saving throw. A creature takes 3d10 lightning damage on a failed save, or half as much damage on a successful one. Furthermore, glass spikes erupt from the ground in that area and remain until the end of your next turn. For the duration, a creature takes 1d4 slashing damage for every 5 feet it walks within the area unless it chooses to spend 2 feet for every 1 foot it moves to avoid the spikes. Once a bolt of lightning has been called down in this way, this property of the spear can't be used again until the next dawn.
The lightning struck the ground, and there it remained.
