Kingdom Hearts Union χ - Nightmare Cy-bug (No Avatar Board)
5This was probably the fight that took me the longest to figure out. The reverse absorb was not a problem but the power reflect was a major hurtle and forced me to go digging for different medals. Up until this point I had been solely using Kairi, Goofy and Sora & Pals to power through everything but it was obviously I needed to find different tanking medals. As I was looking through various magic medals, I happened to notice that Illustrated Kairi was given a "Next medal turns Magic" buff when they upgraded it SN++ and it was that change that saved me a lot of hassle.
Since I could make one of my power medals magic, I just had to figure out the order. Since I needed my Sora and Pals for the Paralyze immunity, I was able to slot Kairi there and then just throw Goofy onto a random slot early on the keyblade. Since Goofy was on an unboosted slot, it does no damage which means no damage is reflected. Luckily for me, the counter proved to be a non-issue. It just doesn't do any damage because of Defense Boost 8 and even then, the Cy-bug's low blue count means it always triggers after my last medal.
