Somehow, both the Deathwing fight at Akuwa Town and Madame X at Blacksteeple so far ended with ma girl Banette dealing the final blow with sucker punch.
The Deathwings were standard enough - nothing seems to have changed much, so I got 3 endeavor sturdy donphans and 1 feint pikachu, 1 meat shield pokemon (sorry Meowstick!) and Banette for priority.
And me being partial to ghost-types, my go-to strategy for no items Yveltal in v13 was always two Cursed Bodies, a screen setter, and a bit of luck, so I was majorly surprised when I found out Yveltal also had Hurricane for 13.5. But then I remembered my Banette, whose role is usually to do Shenanigans against bosses, actually had Curse on it! So I Curse-bodied Decimation with A-Marowak, prayed for Hurricane to miss, set up Curse, then stalled it out. How's getting cursed twice feel, Madame X?
So far the hardest of the "impossible" was Madelis using Melia's early game team. The AI change made it so that the prevoius pray-for-two-omniboosts-then-yawn strategy didn't work, so I was majorly panicking - only for me to realize Melia also came with Bunearly this time like, waaaaaaaay too far into the challenge. Thankfully, after that a bit more grinding made it work.
I did manage to see a TRIPLE omniboost though. Guess that's what happens if you luck-grind for TWO HOURS!
Overall, I really like the new boss battle mechanics - the 2nd Rift Gyarados fight was unexpectedly hard, not gonna lie, like I can't believe we actually got infernal field for that - but overall it was much more enjoyable compared to v13 so far. Being able to see how far I'm into the shield is a good change, and it makes setting up momentum much more easier and enjoyable.
Oh, and a bit unrelated, but that 999 black prism mystery contract (which I'm never gonna look up, even once the guides are updated and such) is a very good secondary motivator for me to actually try a living shiny dex for rejuv as I did for reborn (as far as this version allows for, of course!) this time. I can't wait to grind myself to death.
