I think its weird that its recommending using Humming Arcane Stone as Feral as it requires magic damage to proc. It doesn’t seem to do much damage at all. I believe the reasoning may have to due with it being ranked up well if you have the crafted helm that does fire damage every few secs with the embellishment (which i don’t have).
The humming arcane stone does not require magic damage as far as I know. The spell data indicates that it triggers on both melee and ranged abilities as well.
"Dealing Magic damage " are the first 3 words on the tooltip.
Did a boss fight in which i did an average of like 60kdps overall, and the Humming arcane stone did like 1% of the damage overall, while DH and shamans who did less dps, the gem did like 4-7% of their damage.
My damage went up considerably using another gem in my bag than the recommended Humming arcane stone.
