Knock and True Seeing


Rules Questions

Grand Lodge

At my last gaming session we had a few rules debates that took several 10's of minutes each to reach an agreement.
The DM asked me to forward the question onto the Paizo boards to get feedback.

First argument was on the knock spell. If a doorway has magical traps cast upon it do they go off when the knock is cast on the door? I had said that if the spells were cast on the door itself then the spells would go off, and if the spells were cast onto the lock then they would not.

Second argument was on the true seeing spell. We came upon a room dominated by a golden statue of dragon. This statue had one curious feature, the eyes were real and moved around like a normal dragons. Asking the statue a question and how to respond in eye movements showed us an intelligence within. caster casts true seeing, this is where the debate started. The DM had transmuted a red dragon to a golden statue for the sole purpose of us to dispel the magic that transmuted the creature for a fight. The DM's question is would true seeing show the statue as a dragon, and if it did would it show it as a red dragon?

1) Traps won't go off until you OPEN the door. Unlocking it wouldn't set off anything.

2) I don't think true seeing would reveal anything. The dragon doesn't have an illusion cast on it - it IS a statue.


From True Seeing:

"You confer on the subject the ability to see all things as they actually are. The subject sees through normal and magical darkness, notices secret doors hidden by magic, sees the exact locations of creatures or objects under blur or displacement effects, sees invisible creatures or objects normally, sees through illusions, and sees the true form of polymorphed, changed, or transmuted things. Further, the subject can focus its vision to see into the Ethereal Plane (but not into extra-dimensional spaces). The range of true seeing conferred is 120 feet."

Seems pretty clear to me. True seeing allows the caster to see the true form of transmuted things. A red dragon transmuted into a statue (especially one that will be turned back into a red dragon with a dispel magic) certainly seems to qualify.

(1) Knock. Depends on the Trigger. Knock actually opens the door. If the trap trigger is "mechanical proximity" (slightest change in the air), then yes, the traps go off as the door moving will do this. "Sound" is iffy, depends on how oiled the door is. I would argue "touch" would set it off as the trap and door have moved. Other triggers, such as "alarm", rely on the presence of creatures and would not be triggered by knock.

(2) True Seeing. The spell itself says it reveals the true form of "transmuted" things. Your caster would see a red dragon and know it wasn't really a golden statue. However, he wouldn't know the dragon's intent or so forth. Suppose anyone with Knowledge Arcana would know Red Dragons are usually hostile!


I would have to say that a knock spell would not remove the trap. When exactly the trap goes off depends upon what the trap is. Is the trap itself triggered by opening the door, turning the handle (if it has one), or unlocking it? If it is not spelled out then I would say casting knock triggers the spell. Another way to think of it is remove knock from the equation. Would a person walking up to a locked door and trying the handle trigger the trap? Does the door and/or trap say someone with a proper key does not trigger the trap or do they have to do something before unlocking the door.


Herpaderp, yeah, I was wrong :<
