There needs to be an in-game Bestiary with drop lists

[LibitIncarne]

Bestiary could include bi-color gem traders in the list of locations to obtain skins/hides/etc.

Honestly, really struggling to understand why this doesn't exist. It's a design misstep, imo.

Alright give 5 examples of MMOs that have a bestiary like this. Bonus points if you have any examples that were first released before 2.0 did, double bonus points if it was before 1.0.
