To avoid making the boulder kill mobs, maybe have it squish critters instead?

the peterrodax hatchling was alive, and loque, gondria, articus, ghostcrawler ETC are all dead animals but we can tame them

Loque is divine, not dead. All Hail the Divine Feline!

Being more serious, I have to second the skele-windserps. We can tame the skeletal eagles in WPL, and I just rolled up an undead theme hunter where that would fit perfectly.

Might want to do a little more research before taking such a hard stance. From Har'koa's WoWWiki page:

Har'koa is one of the Loa goddesses of the Drakkari, taking the form of a great Snow leopard. Her children were twisted against her and became the Cursed Offspring of Har'koa. She swears revenge on her captors. Her mate is Loque'nahak, who wanders far from home.

Loque is, at the very least, an exception. Skoll, the other spirit beast who isn't translucent, is likely another exception, although he doesn't have a known backstory.

And on principle, I'd hesitate to label Ghostcrawler as "dead," since his namesake is not - he's likely more of an embodiment of the real GC's spirit in game. That one could be argued against, but that's my take on him.

I never really considered any of the spirit beasts dead. "Spirit" (in my view) doesn't necessarily have to mean "dead"... I always considered it sort of like they're in touch with another plane. You know how WoW lore talks about the elemental planes? Emerald dream? etc. Sort of like that.

As for the original topic, I'd adore that sort of idea. A sort of "uncommon" artifact that has a chance to drop when you dig up other artefacts or something. Use it to spawn a mob which you could tame or kill for a bonus.

To make it more appealing to the general WoW population and favour hunters a little less, maybe it could be like Jadefang, where killing it gets you a minipet? I'd love to see that, especially with the gem cats.
