THe armour of Brutus has actual stats, while Altair's is purely cosmetic and will take on the stats of whatever armour you're really wearing.
no
you can only change the color and the armor type, then you get Altair's armor, so no.
Go to your hideout and equip the desired armor
No, and i was surprised that it never needed repair but it would probably cost a lot since it was Altair's armor.
Altair's armor is under ground at the villa, but note you need all the seals out of the tombs to get it. they are not at the same place a few at venetie and romagna and one will jou get when you play further in the game
you must complete all 6 tombs in the game and place the seals you get in the chests (in the tombs) on the statues of the assassins in the monteriggioni villa and the gate will open to receive Altair's armor. http://www.youtube.com/watch?v=imRdq4gU4pg
Well in the begining of the game, you have Altairs Armor but you lose it at the Villa Attack so to get it back you have to go to uplay and get it from there... But it says Altair Armor but its not really Armor so i recommed getting Brutes Armor which you get from get the keys from the romluses Later in the game and the Armor has the same Stats as Altairs Armor.
You can get both Altair's robes and armor by going to the main menu and selecting Uplay. From their select Rewards and then assassin's creed brotherhood. From there you should see Altair's armor and robes which you can buy if you have enough points.
technically it isn't the armor that's black it's the suit. Plus it looks cooler and you can't find black dye in any city.
I have never heard of exactly why the designers did not make it to where you could separate Altair's armor. It does look pretty beast as is though. It would be cool to experiment with it though.
Head over to Monteriggioni or The Villa, and as soon as you enter the main entrance take a left and there is all your previous weapons and armor in separate rooms right next to each other almost.
It's called the Armor of Brutus, as in the guy from Shakespeare's play that conspires to kill Julius Caesar. It has two eagles on the chest plate, an eagle shoulder guard, fur covering for the throat, and a red and gold theme.
