Final Fantasy Hacktics

I am curious to know if you've made any changes to the Riovanes Castle Roof battle with Elmdore and his two assassins (where Rapha mustn't be KOed or it's game over). Are there any stealable items or must-haves? I know you made the Genji items available for stealing later on versus Elmdore so I was wondering if you did the same thing here. The reason I'm asking is because Rapha ended the battle with a single cast of Mantra before I could even get a turn on any of my units; she landed almost everything on one of the assassins and made all of them run. Biggest laugh I've had in the game so far.

I just think that the monsters are overtuned for the early game. Those added statuses and passive abilities are a major pain if you're trying to farm JP on non-combat classes.
