Having integration with JER would be very useful for the mod's playability, as there are many special drops from specific mobs that require opening the wiki every time. The wiki is great though!

fixed in 7587c00, should be working in the next update.

No chance for a 1.12.2 backport? :)

Sorry, it's quite hard to maintain multiple versions for single developer :(

I was specifically asking as I plan to add your mod to Hexxit II, but I fully understand ):

Hmm, indeed it seems more complicated in 1.12.2 - feel free to drop it

Hmm... JER integration seems to be much more complicated in 1.12.2 than 1.16.5.
JER 1.16.5 automatically import all loot tables where JER in 1.12.2 you have to manually import them.

nvm, I just made it work.
