I made a bestiary and collections window. Here you can see the three different tabs of the bestiary window. They are unlockable in game via the premium shop, but the tracking has happened from almost day 1, so any monsters/npcs you have killed have been tracked all along. I have been planning this feature for a long long time. I always wanted a bestiary in games.
To expand it from just a counter, I really like the idea of monsters dropping faction shards. Eventually maybe I can have them be spendable currency or give certain bonuses towards those factions. I am open to suggestions on ways to make it even better.
I really need to just push the new version already. Maybe will work on finalizing the code this weekend so I can deploy the following weekend!
