can someone add this info to the page? not nullifying buff sounds seems like something that should be pointed out here.
I did some testing with a friend on the slumbering dragon crest ring. Weapon buffs will still be heard around the same distance you become visible with the obscuring ring, at least for players anyway.
lightning was the easiest to hear and most likely to stand out
fire was hardest to hear and could be mistaken for ambient fire easily
kinda ruins obscuring ring and slumbering dragoncrest ring backstab tactics if you can't buff without risking the other person hearing you
