You're forgetting about the part where it says: "Deities and unique beings
cannot be controlled in any event. An uncontrolled being acts as it pleases, making the calling of such creatures rather dangerous. An uncontrolled being may return to its home plane at any time."
And then "A controlled creature
can be commanded to perform a service for you."
This is all after the part we're discussing, where it says "Deities and unique beings are under no
compulsion to come through the gate, although they may choose to do so of their own accord."
Also, in
www.d20srd.org, the bolded compulsion part links to
http://www.d20srd.org/srd/specialAbilities.htm#charmAndCompulsionWhere we can read
"A compulsion
overrides the subject’s free will in some way or simply changes the way the subject’s mind works. A charm makes the subject a friend of the caster; a compulsion
makes the subject obey the caster."
In other words, a creature under your compulsion is under your
control. It's being
commanded by you to fulfill a certain task.
To me, at least, this seals the deal: Gate has two effects.
The first effect, is to make the gate appear exactly next to the creature you're calling through it, and forcefully pull it through, this is a given by this sentence:
"By naming a particular being or kind of being as you cast the spell, you cause the gate to open
in the immediate vicinity of the desired creature and
pull the subject through, willing or unwilling."
The second effect, is putting the creature under a compulsion to perform "any other actions that can be accomplished within 1 round per caster level counts as an immediate task".
The caveats for this compulsion effect to work are very well defined in the spell:
- Does not work on Deities or Unique Beings
- Can't be something that will take more than 1 round per caster level.
Everything else, is fair game, and the creature has no way of saying no. This is strong evidence that there is a mind effecting component to gate, and it's what seals the deal for me.
Also of note, is this oft overlooked sentence, under
calling creatures use of the spell: "This use of the spell creates a gate that remains open
just long enough to transport the called creatures."
This means that the gate DOES NOT REOPEN for the creature to go BACK to where it came from. If it has a means of planar travel available to it, it can use those, and if not, it has to find one. The rest of the description just says "The creature departs at the end of the spell.", but bears no mention of the gate reopening, which is implied by the previous bolded sentence.
This leaves me with the conclusion, that there are two main possible weaknesses to the Gate spell:
1 - You can negate the compulsion, and the creature will no long be bound and, as by text of the gate spell "An uncontrolled being acts as it pleases, making the calling of such creatures rather dangerous. An uncontrolled being may return to its home plane at any time.".
2 - Gate provides for a way IN for the creatures, but not for a way OUT. Once the task is completed, the compulsion effect ends, and the creature is then uncontrolled.
In the context of this situation of Fighter vs 4 Ancient Gold Dragons, this means that with this interpretation, the fighter just needs to evade the dragons for 20 rounds (Wizard's CL), before they are no longer under the effects of the compulsion. Then, you have four VERY pissed Ancient Gold Dragons that got forcefully pulled out of wherever the hell they may have been and commanded by a Wizard who is individually weaker than even a single one of them.
Do note that Gold Dragons are good, and probably wouldn't take it kindly to be ordered to slaughter someone who, as far as they know, have done nothing wrong.
