Draken fangs

I’ve killed exactly 50 drakenfyrs and I have a chance IV and 2x drop I haven’t gotten the sword and I also haven’t gotten a single dragon bone or dragon thing. It’s really starting to irritate me here cause I’ve spent most of my Thanksgiving break grinding this boss out. Am I glitched or something because I haven’t gotten a single drop from it other than gems and dragon scales or do I just have trash luck
