Mendoza main mission the Farewell
This is a Feature challenge
It’s the easiest challenge ever of all time.
You’re choice the Mercer guard elite outfit or waiter
I chose waiter as starting location. You don’t need any equipment, I did bring a durian because the waiter is a trespassing area in the kitchen in Yates mansion and the 2 cooks are NPC. Use Durian or wait for conversation to end then get the banana on the table.
Then walk to the fire place in the same kitchen at the other end and toss the banana in the fire and the challenge immediately pops up.
You can quit at that moment, I chose to finish the mission.
Subdue from around the corner upstairs as Yates wife comes up first drag put in closet
Then subdue from around corner Yates drag by the closet door then snap neck so the guards on the steps don’t hear. Put in closet his body.
Grab the lethal poison from his bathroom. Go to the bar where you spawn if you have waiter disquise starting location chosen.
Get the Pinot Noir wine from the storage to the right of the bar , place the wine on table, serve as a bartender, poison glass of lethal poison. Serve Vadal when prompted, while she is in the middle of passing out walk outside to the right door and walk around and take any exit, I chose to dance with Diana

waiting for Yates and Vadal and the cooks is what took so long.
