So, I tried Poaching today.

[Jowy]

There will be a battle related to the Cloud sidequest in due time. You'll need Move-Find Item to get the best spear and shield in the game. Make Rafa your locator slave, and head to the top of the two tallest pillars using your newest unit as a stepping stone.

When you destroy a monster with Secret Hunt as an equipped ability, using only regular attacks to defeat it, you'll get a message stating that the poach was successful. You can then go to the Fur Shops across Ivalice and get some rare goodies. Most noteworthy is the Chantage, if you missed stealing it from Meliadoul or just want an unstoppable Amazon army.
