Paris Tungsten Ingots Wealth Locations
Manoir des Fleurs Rogues - Tungsten Ingot
You’ll find the Tungsten Ingot at Manoir des Fleurs Rogues underground, which can be accessed from by climbing down a ladder located in an outhouse to the southeast of the manor, as shown in the screenshots below. Once you’re underground it’s a fairly simple path to the room which contains the wealth chest, but you will need to avoid some rats along the way. You should be able to run beyond them easily, but if they begin to overwhelm you can always attack them with melee strikes to force them into nearby sewer grates.
Once you’re in the room with the wealth chest, you’ll find a hole in the wall to the northwest. Slide under here and destroy the pot in the corner of the room to reveal the key to the chest. You can then slide back under and open the chest.
Saint-Merri Crypts - Tungsten Ingot
This ingot can be found int he crypts of the Saint-Merri church. To enter the crypts you’ll first need to take the key to the gate of the chapel from the eastern side of the church interior. You can then make your way down the steps where you’ll find a number of rats. You’ll need to attack the rats to force them into the sewer grates, then cover the grates with the movable barricades to trap the rats. Move the second barricade to find a fire pot behind it, or use the Incendiary Powder Trap ranged ability to destroy the wall on the northeastern side. Once you’re in the room with the poison, throw a torch at the poison to disperse it and force the rats into the sewer grate. If there are some rats remaining, just attack them with melee or ranged to force them into the grate, then cover it with a barricade. You can then access the chest behind a final barricade in this room.
Grand Chatelet - Tungsten Ingot
This ingot can be found in the military barracks at Grand Chatelet, in the northern part of Paris. You’ll find the wealth chest at the top of the wooden watch tower in the camp, but you’ll need to take a key from a Standard-Bearer who patrols below to open it. You should be able to assassinate the Standard-Bearer by jumping from the rope wire which is attached to the tower. Otherwise, you can eliminate the entire camp.
