im collecting elemental runes to make the tablets for the legendary ring quest line, if you do lfr and normal and heroic and mythic, do you get them from each mode or is it once a week type thing, also can you redo lfr or anything to get more

1 time per boss per week mode dosent matter, if you have gotten runes of a boss you are locked for him

wow a non troll answer. ty bud. next question. i did the lfr for blackhand, then got a quest to do that requires me to kill him for his arm, did lfr again but no arm off him. wat do

wait till next week sadly
