I have been blocking attacks for about 2 minutes straight here and my revenge meter hasn't filled in the slightest, I'm at the last area standing between the 2 captains and all the soldiers, blocking every single attack. Is there some way to gain revenge in this trial that is unique?? Because blocking or getting hit doesn't do jack.
Since I can't find a way to delete this post I'll just leave this reply - could help someone in the future anyways. For the zone attack trial revenge activation optional objective, once you cross the ship if you turn to the right you'll find a Peacekeeper and a Warden available for you to block and build revenge on, completely missed it my first few times.
