Psionics VS. Magic-A screwball situation

[Balabanto]

All right! Here's one for the ages:

A master psionic sets up a telekinetic force bubble around an object, person or thing. This field is A) Coextant with the ground below or B) Stops at the limit of the psionic's vision, or C) Is a Sphere.

Assuming that any of these is the case, what happens when an Earth Warlock casts River of Lava along the area containing the field? If the River immediately destroys the bubble, what happens to the material and/or things inside? And how quickly does lava fill the surrounding space?

[Balabanto]

This is what I thought, too. But one of my players argues this:

The Bubble is a sphere, so the sphere sits in the middle of the river. How long does it take for the lava to cover the ensuing piece of ground within? My argument is that it's instantataneous, because of MDC damage vs. SDC earth. BUT, the damage only happens once a round, so the player argues that it takes additional time for that chunk of ground to sink into the lava before the damage occurs again, because of the way Telekinetic Force Field is worded. He argues that it creates an island effect, because the force field displaces carpet of adhesion by having the carpet run up along the line of the sphere. (Granting the psionic a chance to escape before they fall into the lava and die.)

My real problem here, of course, is that Telekinetic Force Field is unclear as to whether it stops when it hits the ground or not. It SHOULD, because Psionics are based on line of sight. If the psionic is running Mind's Eye or has the ability to see through dirt, then sure, a sphere is possible, but other than that, it should stop at the ground.

It's simple: it does the normal damage every melee round until the bubble is depeleted. I'm not sure why your asking?

c, sort of. The bubble only has to enclose the target, and running flat along the surface of the ground. The only limitation is that the TKFF can not move and the TKFF has to be with in the LoS of the PSI who created it. There is leway to run the TKFF under the feet of people. There is no has to be connected to the grounding PF2 HU2, NB, NS, RMB, RGMG. [ SF, S, N&S, MC, BTS1 have nothing to say on this.]
What it says in RUE only counts if 1) you are play'n rifts and 2) you are using the RUE rules set.
Besides, the way it's worded, the subtext says "No you can't make floating platform in the air to stand on with it."

part 2) The RoL would flow around the TKFF till the TKFF lost all it's xDC.

Well, that clarifies things.

Oh.

It says clearly it's a bubble, not a hemisphere. I always pictured you as standing on top of the feild in the first place.

In my game TKFF is exactly like those. Its a Circular Force Field Bubble, that HAS to connect to the ground. While CoA could be cast upon the shield on the inside or the outside I do agree with also.

The River of Lava does Damage in accordence to its spell description. The Force Field does not sink regardless of the amount of ground that it loses underneath. And once its Overall MDC is depleted it simply vanishes .. And either the Character's fall into the River of Lava (an prolly die) or the force field berely makes it threw the duration of the River of Lava and the PC's live.

As the GM your word is absolute in context of the Game world. This is something your PC's need to be aware of..
