User blog comment:Broman178/Merlin's ability to sense magical objects./@comment-5350801-20120811180037

I just re-watched The Wicked Day last night. Seriously, this is all by coincidence. Again boyfriend is finally into Merlin and we're going through 2-3 episodes a night. But Morgana stated that the pendant that was put around Uther's neck was charmed. Maybe charms aren't as detecable as items that have been spelled.

Here's what I was also thinking based on another item you forgot. Morgana's bracelet that Morgause gave her to keep her dreams a way. I believed Morgause said a spell over that.

Based on that and the items that you originally stated, maybe the idea is more about how long they have been around to collect magical ability. We know the Phoenix Eye was if it was in an old book Gaius had. The Rowan Staff may not have been in a book, but if it was carved from the Rowan tree on the Isle of the Blessed it is safe to say that the tree and staff have been around for centuries. As for the The Cup of Life, and the Mage Stone, we can only guess. But I would think objects that powerful, to save a life and turn lead to gold, respectively, would have to be around ALOT long than a few years. I would think centuries.

The point is, maybe the word "very powerful" is more subjective. Maybe the idea of "very powerful" are objects that have been around forcenturies, and not just spelled and/or charmed to work a certain way.
