User blog comment:Rainb0wSprinklz/Problems with the final confrontation between Granny Rags and Slackjaw/@comment-174.17.20.5-20150129160322

I managed clean hands, stealth, and mostly flesh and steel achievements at once on this level. So no killing, wasn't detected, and only having the original blink power you are given, no others. Here's how:

It doesn't matter if they see you when you first come in, neither granny nor slackjaw is hostile. Run around, collect stuff until you're ready to start. Get the cameo, save game. Trust me. put it in the furnace and she teleports to the room, this does not ruin stealth, it doesn't count as a detection. It won't until after the cameo is destroyed, after she talks, there's a flash and granny stumbles.

Get out of the room before then, she doesn't seem to notice you as easily outside. Then when she teleports outside nail her with a sleep dart, get the key and drop her somewhere rats can't get to her. On the bed or the table in the back room. Free slackjaw and be on your way.
