I play a Carry Alchemist, as he is very powerful with his insanely low BAT.
Treads / BoT
Vladmir's Offering / Heart / BKB
Burzia / MKB
Desolator and Acid Spray surprisingly devastate any hero, especially if he is stunned with Unstable. And after you get Assault Cuirass, you are a much better tank with very high threat factor that cannot be ignored. So, if you were to play him as a tank, I'd get something to make your presence feared, but also able to resist tons of punishment. (Armlet, Heart. Vanguard loses a lot of effectiveness later on.)
Armlet seems like a good choice on him.
However after watching at least 5 pro replays of Alchemist in action, none of them got armlet.
I really think armlet is more for pubstomp than competitive plays.
Since Alchemist really shines as support/tank.
His stun has such a low cooldown, it is insane.
And he is not like Centuar or Bristleback who everyone can ignore without radiance, everyone still want to kill Alchemist first just because of acid and nuke
