Is Resilient Sphere affected by Gravity...


Rules Questions


According to the spell description;

Quote:
"The sphere cannot be physically moved either by people outside it or by the struggles of those within."

Does this mean, that if the spell is cast upon a creature that is flying, the sphere will appear in the air, and remain motionless until the spell is ended? Other examples would be a falling creature, a creature in water (would the sphere rise to the surface, sink or remain in place?), or a creature on a steep slope (even though the it is a sphere, it would not roll down the hill?)

If it were to be ruled that a Resilient Sphere could fall, what weight would it be?


Resilient Sphere is a force spell effect, and it does not move or follow the laws of gravity. Specifically, it does not move, period.

Resilient Sphere wrote:
A globe of shimmering force encloses a creature, provided the creature is small enough to fit within the diameter of the sphere. The sphere contains its subject for the spell's duration. The sphere functions as a wall of force, except that it can be negated by dispel magic. A subject inside the sphere can breathe normally. The sphere cannot be physically moved either by people outside it or by the struggles of those within.
Wall of Force wrote:

A wall of force creates an invisible wall of pure force. The wall cannot move and is not easily destroyed. A wall of force is immune to dispel magic, although a mage's disjunction can still dispel it. A wall of force can be damaged by spells as normal, except for disintegrate, which automatically destroys it. It can be damaged by weapons and supernatural abilities, but a wall of force has hardness 30 and a number of hit points equal to 20 per caster level. Contact with a sphere of annihilation or rod of cancellation instantly destroys a wall of force.

Breath weapons and spells cannot pass through a wall of force in either direction, although dimension door, teleport, and similar effects can bypass the barrier. It blocks ethereal creatures as well as material ones (though ethereal creatures can usually circumvent the wall by going around it, through material floors and ceilings). Gaze attacks can operate through a wall of force.

The caster can form the wall into a flat, vertical plane whose area is up to one 10-foot square per level. The wall must be continuous and unbroken when formed. If its surface is broken by any object or creature, the spell fails.

Wall of force can be made permanent with a permanency spell.

I would think that if something as simple as gravity could move the Resilient Sphere, then a strong creature should also be able to move it. However, Resilient Sphere does not move, just like Wall of Force.


I've always seen Resilient Sphere run as being unaffected by gravity, but YMMV.


As a force effect, resilient sphere is entirely immobile and is unaffected by gravity.

Otherwise you could drop walls of force on people. It doesn't work like that.


though it does beg the question; in a setting where it is established that planets move, do subjects get thrown either into space or through the planet depending on where they are when the spell goes off? And if you place the spell on someone on a ship, does it blow a hole in the back of the ship since a hardness of 30 will exceed anything the ship is likely to be made of?


In my home games, I once added an immovable rod. It was special because it was immovable relative to the center of the galaxy, instead of relative to the rod user.

I really like these kinds of questions. That said, if you let flying creatures hover on a ship (or keep up without blowing their movement each round), you should probably treat force effects the same way.

I always though that magic effects, where 'immovable', if they were relative to the galactic scale rather than the relative scale would probably be unobservable to most mortal creatures as the effect would appear and move away so fast as the be unobservable for the most part.

I always think of magic effects as 'conceptual and intent sensitive' so an 'immovable' effect is relative to the immediate environment it was created into.

Otherwise your wall of force would be a super dangerous battering ram moving at hundreds of thousands of mile per hour (or faster) when it was created if it was linked to the galactic scale rather than local. Which the spell clearly shows it is not.

I can say with all honesty that I do not allow flying creatures to ignore movement of the vehicle they are flying over. If there is a rule somewhere that says otherwise, please direct me to it.
