This mod adds some useful tags that you can use in your mods, as well as providing additional entries to some vanilla, forge, c: and other mods' tags. It also uses a config to 'tag' unfortunately untaggable dimensions. And it also adds a recipe for arrows that uses these tags.
Current compatibility with:
Blue Skies

Believe it or not, I actually got sponsored! Here is my affiliate link https://kcbhosting.com/aff/N3R3SH. Discount code is N3R3SH, same as my username on most everything (except here, since I lost access to my first account). You have probably seen such ads elsewhere, it is just a standard server service, for Minecraft and some other games. I do personally have a server from them and I can't complain. Deals seem solid :)
