Illusions, DC based on Perception or Insight?

[zoggynog]

Hey folks,

I'm working on a "dungeon" for my group. Each room, and the creatures within, are all under an illusion. The place has undead, but depending on if you pass the passive DC for the room, they appear living. Rotten food looks fresh, dead plants alive etc.

These will be combat encounter rooms.

Outside of the initial passive DC check, I plan on allowing them to use an active perception/insight check to further break the illusion on their turns...or after the encounter.

So my question is, when they walk into the room, what do I base the passive DC check on? Insight or Perception? Or whatever is higher?

The few references I can find in the Compendium show, DC checks vs illusions are based on Insight. Perception still feels like it would be more valid though because they are seeing the illusion...not feeling it....thoughts?

Insight, per the skill description itself.

That's just it, they -see- the illusion just fine. That's how illusions work, is by you seeing them.

However, the sense that there is something wrong or not quite right is more based on intuition and 'gut' and thus is covered under the perview of Insight.
