- Three cover kills
- Keep up with Bellec
Talk to Bellec on the rooftop to begin this mission. To safely get down into the area below without being spotted turn right and cross over the windows to reach the side of the area with the gargoyle water spouts and cross them to reach the area with two tents.
To complete the first optional objective you’ll want to kill the three guards in this area from cover. Start by entering stealth mode and sneaking up behind the nearest guard, using the boxes for cover, and when the other guards aren’t looking pull him over the boxes.
You can now stand up to draw the attention of the next nearest guard and use the last known position to draw him over to you and kill him from cover too. The final guard is actually stationary by a pillar in the distance and you can easily get the final cover kill by skirting the outside of the area and take cover next to him for a quick kill.
With all the enemies taken care of you can walk up to the alarm bell sabotage it for a scene.
After the scene ends assassinate the remaining thug and then loot the evidence from the marked corpse. The second optional objective will trigger as a bunch of men enter the courtyard, so drop a Smoke Bomb to distract them and then follow Bellec up the side of the building. Cross the roof and pass through the building, jumping off the balcony to the rope below and crossing to the roof.
After Bellec drops to the ground, toss a Smoke Grenade by holding R1 / RB to aim the grenade directly between the two guards and then kill both the guards. Follow Bellec through the streets, dropping bombs and killing the guards you encounter until you trigger a scene.
Bellec will take to the roofs now, making following him a bit more difficult, but the easiest way to keep up with him is to stick to the roofs even if he takes a different path through the buildings. If you do lose sight of Bellec, a waymarker will appear at the Assassin Headquarter for you to catch up.
Once you reach the headquarters, enter and head to the Council Chamber.
