A storm cloud appears at a point within range that you can see above yourself. It takes the shape of a Cylinder that is 10 feet tall with a 60-foot radius.
When you cast the spell, choose a point you can see under the cloud. A lightning bolt shoots from the cloud to that point. Each creature within 5 feet of that point makes a Dexterity saving throw, taking 3d10 Lightning damage on a failed save or half as much damage on a successful one.
Until the spell ends, you can take a Magic action to call down lightning in that way again, targeting the same point or a different one.
If you’re outdoors in a storm when you cast this spell, the spell gives you control over that storm instead of creating a new one. Under such conditions, the spell’s damage increases by 1d10.
Using a Higher-Level Spell Slot. The damage increases by 1d10 for each spell slot level above 3.
So the space requirement to accomodate the spell is gone? How does this now work if cast in a space smaller than the volume of the spell? Does it just fill the entire space?
Think it got the baldur's gate treatment, that limitation was annoying. I like to view it as if you summon a cloud that shoots the bolt and it dissipates til called on again. Great spell in baldur's but ok on table top.
They still haven't clarified this:
"A storm cloud appears at a point within range that you can see above yourself."
Does this mean you cast it directly above yourself at up to 120 ft altitude, or does it mean you can cast it up to 120 ft away from you as long as the origin point is higher than the top of your head?
The wording seems pretty straightforward to me. The origin point of the spell can be any point that is within 120 feet of you and above you. I don't see that there's really any ambiguity there.
I agree, especially with the legacy spell specifically calling out directly above you. That was intentionally taken out, along with the space restriction.
