Well, guess I better find a solution to my failure to beat G19. Time to get r1 final hit and attempt to cheese it that way.
I'm going to hold devcat to high expectations on G20 for taking it so long.
So I haven't seen anything in this thread that says you've beaten the last mission there. I found a technique that makes it possible for any character to do the mission.
Due to the fact that judgement blade does a nice fixed 40% damage to the girgs, what I did is I stocked up a crapton of HP30's to deal with the damage they can do for free on you and I did this:
I ran to the edge of the map, as the edges are like this giant square that the girgs have to run around with you if you lead them around. Keep running laps around the map for a bit until they line up for you. I don't remember the exact timing, but I usually used judgement blade whenever I was a decent distance from them and they were in the middle of some form of animation so I had the time to draw the blade. Because you're strafing them around the edges of the map, only one usually gets to be in range to attack you at any given time due to the fact that the other one is usually lagging behind the other one having had done some form of attack. Repeatedly spam judgment blade and don't give up if it takes a bit to get them off, it starts becoming easier once you get the hang of it and discover the best moments to drop the sword on them.
