Detained

In just a matter of seconds after taking the suspicious-looking pill, Emery could feel waves crawling down his body. A prominent sensation of weakness permeated every inch of his body to such a degree that his knees almost failed him. 

Iff that wasn't bizarre enough, the spirit energy coursing through his entire body also suddenly felt as if it was drained away. At this exact moment, Emery was sure that if someone were to attack him, he would not be able to do anything.

[Your power has been restricted]

[You have been greatly weakened]

[Emery Ambrose]

[Battle Power: 152 (51)]

[Your body is unable to channel spirit energy]

Whatever it was he just ate had cast such a powerful restraint, to the point he discovered he couldn't cast any spells at all. 

The Ouroboros magus added.

"Now, you will hand over your items."
