Of Toil and Taxes is a main story quest in Assassin’s Creed Mirage.
Your objective is to find and assassinate the Tax Collector.
Here’s a walkthrough and guide of Of Toil and Taxes in AC Mirage.
Rescue the Perfume Merchant
First of all, go to the Perfume Merchant. Her location is shown in the map below.
You’ll see some guards harassing her.
To rescue the merchant, you can either bribe the guards or assassinate them.
I chose to throw a smoke bomb and killed all of them within the time frame. It’s a good way to prevent notoriety.
Once they’re dead, rescue the merchant.
Find the stranded merchants
Now, head south of the city to find the stranded merchants. It’s near the fast travel waypoint as shown in the map below.
Speak to the lead merchant
You’ll arrive at an oasis. Talk to the lead merchant.
Investigate the merchant site
Next, use eagle vision to investigate the merchant site. The clues should be in red color.
Also, you need to talk to two of the people there.
When you’re done investigation, talk to the lead merchant again.
Escort the merchants to the Karkh Gate
Get a camel and follow the merchants to the Karkh Gate.
On the way there, soldiers lie in ambush. Protect the merchants by killing the soldiers.
Once you’ve arrived at the gate, speak to the lead merchant again.
Assassinate Al-Anqa the Tax Collector
You will then learn of Al-Anqa’s location as shown in the map.
Head there and you’ll reach his place. There will be guards all over. You can eliminate some of the bigger guards by hiding in the bushes and whistling for them to come over.
One of the guards at the back will drop the mansion door key.
I used focus assassination to kill all three guards at the back.
Then, use the key to enter the mansion.
Go inside and you’ll see two guards. Take them out.
Head upstairs to assassinate the Tax Collector, i.e. Al-Anqa.
The quest ends here.
