I've said it a few times in the past, but it's been a while so clearly I need to say it again. If I ever stop hosting Boss Battles I'm going to release all the content I've personally made. However, the Xana sword was not created by me. The model was created by Aware and the animations were done by Carbon Zypher. If they both were to agree to release it, then that would be their own decision; however, up until now they've decided to only entrust it with Boss Battles as a mechanic to continue to make the server unique. My general philosophy is that as long as we're actually hosting, releasing the content will only be detrimental since it'll split the playerbase up with any other people who decide to host all the exact same content. As with many games, the best play experience frequently requires a suitable amount of other people to play with. If the the playerbase split up into a bunch of different servers, the most likely thing to happen is the genre dieing as a whole due to lack of actual participants in any particular server.
Did only add on I know for like a boss is Badspot and Ephis weps and Kaje Badspots d wand sword is also released and I will post it if you want me to.
