|Job Trait Information|
|Description||Lowers chance of being detected by enemies.|
- Nothing about this job trait has ever been quantified.
- It is observed that monsters "detect" and potentially aggro players about once per second.
- Therefore, it is theorized that this Job Trait gives a percentage chance of remaining "undetected" at these windows.
- JP Wiki states that one of the following is true though it is hard to be clear which: either it narrows the fan shaped aggro cone for visual of about 60 degrees or lowers its distance or possibly both. Testing could reveal how it effects it and it is stated to only affect visual sensing range, not sound. Testing could be complicated in that it seems monster level and type can play a roll in the detection.
