Knife of Dunwall achievement question

[Fridge Guardian]

Hi people I just bought the DLCs for dishonored and I was wondering if using Daud's "call assassin" power affects the achievement which requires you to beat the game without alerting anyone. Thanks in advance, I wanted to know because if it doesn't break the achievement that would make it a great help.

I'm in the middle of my ghost/clean hands playthrough of Knife of Dunwall, and I just did a quick test by using Summon Assassin on a guard right before completing a mission.

It registers as a kill, since you're obviously responsible for the death, but as long as you stay undetected you will keep your ghost status.

Thanks for your help Ladez, that's great news ^^

I did this one today and I had an issue with it where I finished Knife of Dunwall and all the missions said I got Ghost with no alarms but I didn't get the achievement. My theory is that
When rescuing the assassins, I didn't take out the patrols and when they came by, they saw the assassin missing and went to alert, and this counted against me.
Not positive, but I ran it all again and got it the second time around. Just something to watch out for.
