If someone tried to touch the oil with their bare hand, they will find it not only oily, but sticky and strangely a little gooey as well. But upon withdrawing their hand—or anything solid for that matter—the oil will follow for a short distance before it retracts back onto the wall. This is one of the main reasons why it cannot so easily be wiped away or even scraped off.

As for magical vibes, it does have a hint of darkness, and there will be a sense of sorrow or anguish that will envelop the person. If linger too long, the person may risk being trapped into the strange oil...

However, it doesn't always happen so it's a bit unpredictable in that regard.
