Why was the horn of the wild was disabled? All it does is destroy ground vegetation. I'm just curious, because if it ignores claims or something like that and that's why it was disabled you maybe wanna disable the drum of the wild too since it does the exact same thing and someone could just place it on the edge of a claim and give it a mana pulse to destroy stuff like crops. If it was disabled for some other reason, could I at least be told the reason? The horn was very useful.
It doesn't ignore claims. It could be used to completely destroy any build that uses vegetation, or mess up spawn big time.
While it's true that you need the horn to make the drum, some people already had the horn and disabling it didn't remove it from them. For example, I had the horn and now I have the drum. It's sitting in one of my chests. If you wish I'll destroy it or a mod can but the people that already had the horn could just make the drum and use it.
I don't think that it will allow you to craft it as long as the recipe is disabled. As for if it is usable after being crafted (by the sneaky who somehow crafted it already) - that's something for a mod to test out.
