Hoopa's Dungeon Boss Locator Buff Isn't Working

[Xouman]

Hi,i have a problem with Hoopa's Dungeon Boss Locator Buff,it says that Baraz's Braviary will show me the direction of the boss room,i did a run and i never saw it during it.

Not a bug, you need to discover more to understand that part.

Oh ok if you mean that the little room inside where Braviary and teleporter are is the key and that we should talk to it and it will show us the ways?

 

I thought that this buff worked from the beginning of dungeon and showed us the ways all the time.
