Thanks! And several hours for sure. Spent a while yesterday morning and evening, and again this morning before I finally hit it. Progress was really slow at first because I had to be so careful, but Encore helped me be more confident in just rolling the dice and still at least getting the base EXP if I got barely survive + damage in one roll, and using transfer rune + rest helped keep SP up on my dancer since the SP drain effect happens often and is pretty much a show-stopper once the item-blocking negative effect hits. Those (along with Rehabilitate on everyone) helped keep the luck train rolling until it finally happened. Before figuring those out, it was just too nerve-wracking (and party-destroying) to keep it up for long in any one match.
