Please, someone, tell me I'm not the only person who felt like a total monster for cracking that cute creature open like a pistachio nut...
I don't know why but I felt awful, I was totally shocked when it happened and the only thing that soothed my conscious was the neat helmet I forged from the beast's ill gotten shell... On a slightly less depressing note, how many of these gentle giants are there? If there's only one, I'll sob for days into this finely crafted helmet.
I feel like I just cracked open a crunchy manatee.
No I did it last night and felt pretty bad. I had no idea what it was, fired a few shots at it, then tested the Aura Whisper out on it and it did not come up as being alive. Was a bit of a shock when my character mined it.

Will try the two piece trick shortly and see how that goes, I have to do the Forgotten Vale all over again due to a glitch.
