Is it actually IN the Feywood or is it before the Feywood? If it's before, my only guesses
would be that, if you're entering from the Paramina Rift, it's the Trickster, and if
you're entering from the Golmore Jungle, then it's a mantis thing I forget the name of. If
it's rare game IN the Feywood, then just go back a couple areas and it's probably be gone.
If it's the Trickster, either run past it or enter from the Golmore Jungle. If it's the
mantis, then it will disappear when the mi***es on the play time are between :50 and :15,
I think. If that's not right, figure out the name of the mantis then look up it's spawn
conditions.
