Belbarrus said:Okay, let's try this approach. Some of you are still not understanding the *concept* of spell types.
Enchantment-Compulsion: The spell forces the subject to act in some manner or changes the way her mind works. Some spells determine the subject's actions (or the effects on the subject), some allow you to determine the subject's actions when you cast the spell and others give you ongoing control over the subject.
While discussing whether or not Fly is controlled through a mental action, you are completely forgetting about the Hold spell itself. Hold spells *Compel* the target, through enchantment to NOT move. The target thinks, "Hey, I can just coast along with my fly spell.", but the Hold Person spell, being and Echantment-compulsion, magically causes the target to think, "No, I will just stay here and do nothing." Whether Fly is controlled by mental action is moot. IF (big IF) Hold person was a transmutation or abjuration spell that held the target (via a force field) for example, then you would be able to still Fly with the spell. But the Hold person spell is a Compulsion that is compelling the target to not move.
You are streaching.
"The spell forces the subject to act in some manner or changes the way her mind works. " Hold changes the way your mind works, preventing the control of any limbs.
Hold person is not the same thing as a a suggestion to stand still. It is not a mental compulsion in the english sense, it is changes the way you mind works. It does not, IN ANY WAY, prevent any thoughts you have. You can think at your body all you want, you mind just isn't capable of controling it. Hold person does not change your thoughts, hence you can still concentrate. The compulsion prevents direct control of your physical body, and that is all.
If the spell physically restrained you (as harden air in Wheel of Time) you would NOT be able to fly and you would be prevented from moving, in any direction by any force.
Hold person does not prevent you from falling. Hold person does not prevent someone from picking you up and carrying you. If you had dominated someone, you could mentally command them to carry you away. If you had previously cast a flaming sphere, you could use it to burn ropes and possibly drop the platform you are standing on, hence moving you.
The letter of the rule is pretty clear.
