So the Minecraft Dungeons mod say it is compatible with this mod. But when I try to run them together it doesn't work. It only gives me the Minecraft item tag (screenshot) for the dungeons gear. It does give me the vanilla enchantments descriptions, which I don't really need. This is running alongside AOF3.

It looks like you're using MC Dungeons Weapons which does not have enchantment description support. The Dungeons Gear mod does have support though. If you look in the tooltip the modid is mcdw which is the first mod.
