Tenser's Floating Disk questions:

1. How does it handle forces from directions other than up, such as someone pressing on it from beneath? Does it count all forces against the weight limit or would it track them separately?

2. How does it handle instantaneous forces, such as a weapon strike? I would assume a Great Wyrm Dragon striking a TFD from a Lv 1 would exceed weight capacity, but game mechanics don't seem to provide options for this.

It doesn't specify defenses or HP or anything, so I'm not sure it can be destroyed by trauma. I'd argue that if it gets pushed or attacked it would get knocked back then slowly make its back back into place.

So to your first question, I guess it depends on what the caster had in mind. Did they cast it upside down to try and plug a hole? Did they try to use it to prevent a door from being opened? Are they trying to lift the stuff onto a ledge? The way I would rule it is that by default it's cast pointing up and can carry the specified amount. Forces from other directions affect it as if it were a weight magnet that gets pulled to the correct location over a period relative to the force applied.

At the end of the day I'd say it comes down to DM fiat, or whatever makes sense in the game, but I would applaud creative uses instead of trying to prevent them, as it makes the game more interesting. Maybe when the wyrm strikes it it spins and flings whatever it's holding everywhere before eventually resetting, and there are rules for damaging items that could come into play.

As to the weight capacity, there doesn't seem to be an indication as to what happens when you go over, but I assume it sinks to the ground and becomes unable to move.

@Dirkoth: To your question, I'm not sure there's a clear answer one way the other. I tried to look for existing rulings but none of them mention that use case.

dirkoth, you are correct that it does not have enough clarity.
Does this spell destroy the ground underneath the wizard if it is cast normally?
The spell specifies the bottom half is 'usually' occluded by the ground. Otherwise the mage would be standing on the sphere - layer of ground destroyed > gravity pushes what the mages is standing on down > that layer is destroyed > etc.
How is "floor surface" defined in this instance?
In the instance of the stairs?
I think that 'floor surface' is defined by the mind of the mage.

As with many of these, it will depend on the GM and/or discussion with the GM. Are spells arcane formulae that have an exact effect everytime? Do they have any adjustment to the casters will? Can the caster make small adjustments (this is the one I allow) with Spellcraft checks?

-----
For floating disk, I would refer to wall of force as a starting point, and 'tricks' as a supplemental.

Contact with a sphere of annihilation or rod of cancellation instantly destroys a wall of force...
Shorthand: hardness 30, 20hp/caster level.
It is a lower levels spell, so GM might rule 20/10.

At caster level 5, a dragon would need to do 130 damage to destroy it in one hit.

As for holding power when pushed up...the base would be the same 100 lbs/caster level. If gravity changed, the spell still theoretically supports the same. If the GM uses normal physics on top of magic physics, any weight currently held by the disk on the other side would add to what needed to be lifted.

Overweight, I would also assume it drops to the ground.

No good rules, and I wouldn't want to make is such an invulnerable piece of shaped force by saying it ignores strikes and efforts to move, but it implies that it does.

In pathfinder, there are some tricks you can do (riding it, using it as a shield, etc.), so there are SOME movements and actions it can do, beside float along behind you.

In general, I would say that it handles forces from above and below without disturbance up to the limit of weight (by caster level). Ie, a bird landing on it wouldn't make it move, a dragon landing on it, would. Same for something gushing up below... no effect until the force exerted would be enough to lift the maximum weight allowance (regardless of actual weight in the disk), at which point, it would lift (exceed three foot from the floor) and dissipate.

Same for a sword blow, mace, etc.. You might tip over a low level casting, but not a higher level casting.
