At the moment I'm working on a huge data pack that adds to the game all weapons, bows and crossbows, artifacts, mobs and bosses from Minecraft dungeons.
At the moment I have already added all existing weapons from vanilla Minecraft dungeons and from DLC. Also added a couple of bows and crossbows with unique abilities. Added artifacts and not a lot of armor. And only 5 new mobs.
So far, all things have Russian names, but at the time of release of the data pack will be released in English and Russian versions.
