Obviously it's no longer as useful as I previously said.
I didn't think it was a bug because it had been like that FOREVER, and because I had used it over, and over, and over again over the course of Kasir's life and nobody ever told me to stop.
As for realism...sure, it's not realistic for someone to be distracted while asleep. It's also not realistic for them to be frozen in place for two hours by a thief waving his hands around and making faces at them.
In its present state I *might* still take it as a thug in order to get some of the stealing done pre-blackjack, in order to give me more time to recite scrolls once they're knocked out.
