Spells: moving out of range
 

Suppose you cast a spell that has an effect on an object or area. And either you or the object move away from each other. What happens to the spell?

For subjects you cast a spell on if they move away from you, the spell should continue. This assume that spell doesn't require your concentration.

But what if the spell requires concentration? Suppose you shape water on a success by 3, then move that water 10 yards from you while you remain stationary. Can you still control that water? Or if you form the water into a long, narrow puddle extending from you by dozens of yards?

Does the distance/range only apply at the time the spell is cast?

Nothing, unless someone passes through a no mana zone.
Yes.

Re: Spells: moving out of range
 

So the very wealthy can pay a bunch of mage circles to maintain a bunch of spells on them regardless of how far they travel from that circle.

Re: Spells: moving out of range
 

Theoretically. You can only concentrate while conscious, but if you had a rotating roster then this is a thing that magic lets you do. Its probably how a lot of fantasy castles in GURPS are protected actually.

Hmm, now I want to play a "kill the mages whose spells are protecting the castle" mission...

Re: Spells: moving out of range
 

Yep. Your typical emperor probably has half a dozen circles maintaining redundant Missile Shield spells, for instance.

Fictional example: Morolan, in Steven Brust's Dragaera books, keeps his flying castle up in the air via a circle of magicians. Yes, he's very confident.

Re: Spells: moving out of range
 

Yeah he was cocky from the beginning. Loved that series and still trying to come up with a good way to handle the Empire magic.
Eastern magic is Book/Path

Re: Spells: moving out of range
 

In one of the early books it was noted that flying castles had been much more common before the interregnum (a period of time when empire sorcery stopped working) and there were still some wrecks about.

Ritual Path Magic, but if you buy a spell as a Technique, you can pull all the power you need for it from the Orb in one turn?

Re: Spells: moving out of range
 

At that point it has got to be cheaper to just enchant an item.
