So, it's nice and explicit that Monk's Robe interacts with Brawlers but for the Strangler Archetype you give up class features that are affected by the robe. However, the way it looks by reading makes it seem like the Monk's Robe could actually sidestep some of the class features you give up just by wearing the robe.
So, for the Brawler (Strangler) which gives up the AC bonus class feature, how does the AC bonus of the robe interact? Do you:
-still get the bonus from a monk of your level plus 5
-get the bonus of a 5th level monk
-get no bonus because you gave that up but are still counted as a monk as far as the robe is concerned?
Additionally, the Stranglers get unarmed strike damage equal to a base-Brawler of its level minus 4 (because it gives up the Unarmed Strike class feature but it keeps Close Weapon Mastery). With that in mind, how does Monk's Robe affect the unarmed strike damage of a Strangler? Do you:
-still get the US damage from a monk of your level plus 5
-get the US damage from a monk of your level plus 1 (-4+5)?
Now, I know which way I would rule them at my table but I'm curious what the correct reading is for this combination.
