How do I unlock entries in Bestiary?
I cannot understand how can I unlock Bestiary entries. I've already level 22 and just reached Westmarch.
I can see Bestiary if I click on my character portrait, but my progress is 0/104, but I'm pretty sure I've already fought some elite monsters and bosses.
Monsters drop Monstrous Essence and you need to collect 10 of them (as you can see on the top right you have 0/10) and then you can use the Horadric Altar to redeem them for a new bestiary page.
