Just use Ash's Blade Storm. It's completely silent and if you don't have it fully upgraded or don't get them all with one cast, it teleports you back to where you were when you casted it without alerting anyone. Took me a total of 3 Blade Storms and one Shuriken for a stragler that was missed because he was behind a wall in the second room. Other than that I cleared the entire last room with a sinigle fully leveled Blade Storm, 30% stretch, and a unleveled consitiution providing 7% duration.
