(Seriously, when else are you going to see an Arcana contest? Wizard chess?) Suffice it to say that the rules don't contemplate this sort of thing I think the on-the-fly call of an Arcana contest was awesome. Now you have to go into an analysis of whether that control is exclusive or not, as ably describes. The contest shouldn't have been for the NPC to get control, it should have been to see if the player could continue calling lightning during subsequent rounds.ДЄs above, the NPC's casting took control of the existing (player-generated) storm. To be clear, here we're going beyond RAW (because you did). RAW summary: the spell says the caster (NPC) gains control of the existing storm, so the caster gains control of the existing storm.Д¬ontinuing onto the idea of an Arcane contest that your group introduced. No problem so far: storm existed, NPC cast spell and gets control, gains 1d10 damage. Then NPC casts Call Lightning which explicitly 'gives control over the existing storm' to the NPC. There were stormy conditions, presumably because the player cast Call Lightning and created them. Two storm-users struggling to control the storm and rain lightning on their foes is an extremely interesting thing to happen, moreso than simply casting a spell and dealing damage - and the player (intentionally or not) and the GM have added to the game by having that happen.Д¬an two characters Call Lightning from the same storm? Yes.Дoes the phrase actually have any meaning other than extra damage and flavor? That specific situation, though, is the kind of thing that these games have a GM for - to apply sensible houserules to interesting or edge-case situations to help support the narrative structure of the game.

But as is, it doesn't actually allow you to do anything.

If a different ability let you do to 'anything you magically control', say an ability meant to be used with Dominate Person and it's ilk, then you could use that ability and the line from Call Lightning together to do something (likely something silly). Since it isn't, you do have 'control over' but can't use it to do anything. To further explain, 'control over' is only meaningful in DnD Rules-As-Written if what 'control over' does is meaningfully defined or has an extremely clear common-usage meaning (like 'swing a sword'). As it doesn't do that in this instance, while it is rules text, it does not preclude someone else from casting Call Lightning while under the influence of the same storm, neither does it allow the Call Lightning caster to move the clouds around, increase/lessen the rain, or anything else. In situations where a line like that implies an absolute control, it goes on to define the things you can do with your 'control over the storm', such as moving the clouds, water, etc. Control is not an exclusive verb in english, although that's the more common usage. When you cast this spell using a spell slot of 4th or higher level, the damage increases by 1d10 for each slot level above 3rd.They only can't if 'control over the storm' is exclusive, which the text does not indicate in any way.Д«y a simple english reading, 'control over the storm' does not exclude others from also controlling the storm. Under such conditions, the spellвЂ™s damage increases by 1d10.ДЄt Higher Levels. If you are outdoors in stormy conditions when you cast this spell, the spell gives you control over the existing storm instead of creating a new one. On each of your turns until the spell ends, you can use your action to call down lightning in this way again, targeting the same point or a different one. A creature takes 3d10 lightning damage on a failed save, or half as much damage on a successful one. Each creature within 5 feet of that point must make a Dexterity saving throw. A bolt of lightning flashes down from the cloud to that point.

When you cast the spell, choose a point you can see under the cloud. The spell fails if you canвЂ™t see a point in the air where the storm cloud could appear (for example, if you are in a room that canвЂ™t accommodate the cloud).
