Help me 1v1 a bonedancer

As earth spec, you'd basically have to hope you find them standing still and not paying attention long enough for you to send a bunch of pets at them. You're only advantage is that you can start casting pets before they're in range for their insta, but assuming they have hastener on, you might get one or two out by the time they get into range if they're paying attention, and then you're basically done since you can't run, can't cast, and they're not gonna die from one to two earth pets. You could maybe try sending pets on their subpets first, which they're less likely to notice, meaning you'd have more time to get more pets off, but even without pets, you're basically dead once they get in range with their insta if you don't already have at least four to five pets on the BD itself.

Ice is possible since it's really difficult to target a theurg with giant ice pets standing in front of them, and they also give you a way to get out of insta range if the BD does get close enough. Air is possible because you can neutralize the BD and pets long enough to get enough air pets out to chain stun.

Basically, earth is not a good solo spec, even if you're going up against other classes, let alone against a BD.
