I'm having a hell of a time trying to capture Mew in Ranger. I've been using Ariados to trap it in webbing, but it always breaks free around the last circle, then flies away. It's the hardest challenge I've had in the game, and I want to beat it so I can get to my neglected Nintendog (you can't save during the Mew mission, so my DS is eternally on sleep).
Does anyone have any advice or techniques? I'll gladly help with any other Ranger problems.
