The ability to briefly seal other players' items was indeed useful. She had studied under Mountains Yudun for two days and nights without rest before raising this skill to SS-rank.

The burst lasts 5 minutes. After the burst ends, that skill enters a dormant state for 24 hours. This dormancy cannot be shortened by any means.
