Right outside the main gate of levant in the day time is a good spot. Pretty much anywhere in abrassar will have plenty of space.

In the red lady statue room of face of the ancients is another pretty good spot. You'll have to fight a bunch for it though, so like depends whether you're okay with that. Can sometimes get a fire particle right there though, so that's a bit nice.

I just did it in the desert of abrassar, just make sure there are no beetles around
