You seem to be confusing trait checks and perception checks.
You need at least 2 awareness for the statue, or having Adaon. It's a trait check so the trait level is the only thing that matters.
Perception, the ability to spot secret doors and traps, is totally different. On that skill, 1 point of Awareness gives a 5% increase, which is the same as 2 points of Intelligence. But that's totally different from a trait check. Perception works in the background, running a check for secret doors and traps every few seconds
Trait checks are only activated during a dialogue box.
