Escape NP

Playing Lycanthrope I have to kind of avoid Nature's Prophet and try to make sure I am with a teamate if there is a tower or creep that he can see nearby, because he is obviously going to teleport to me and trap me in his ring of natural death. What can I do?

Force Staff on melee? Will that get out?
None of the magic immunity stuff works, because I am not the target or am I?

Sorry, to be noobish. I am not sure how this works. What can I do playing vs NP?

A Quelling Blade or Tango will do the trick.

Quelling Blade or Tango. They are cheaper than a Force Staff for sure.

I haven't played NP in while but to answer these questions.
Yes Force Staff will jump you to safety, just like with Clockwerks Power Cogs.
And yes you are usually the target, although it is ground target-able so a good Prophet get get even with BKB up.
Cheapest counter, as has been pointed out is Tangos.

As a Lycan shouldn't you have Quelling Blade already...?
