This is a fix on how to kill Balor with the 1.6.0 glitch.
pretty simple just remember to use a hunters bow, quick bow doesn't work.
1. get Balor low health.
2. hit weak points.
3. finish his HP with the bow (doesn't matter how, you do not need to do stun attack so don't worry if it wont let you.)
4. do 1 light attack hit.
5. do 1 headshot (aim for the 3rd eye.)
6. enjoy your new spear.
