Is the Codex is unreliable I just recently started hunting nest golems. Eventually i got their monster card which clearly shows what items and recipes they drop ( as they should with every monster). But something unusual happened. I continued hunting and i found this I checked the codex to see if it was in the droplist and to my surprise it wasnt. This means that other monsters may drop items that aren't listed in their droplist too. Which makes the codex an unreliable source for tracking drops. What do you think?
