I honestly love the concepts being introduced in this entire battle. Creating a freely accelerated world with mobile plants? A world where gravity was sheer repellance instead of an attractive force? Reanimating discarded bodies of a reincarnate and weaponizing them? All are pretty clever twists that could raise a lot of eyebrows.
Unfortunately, twists are only twists if there's a setup to begin with. Can't twist a thread without a thread. And, unfortunately, this final battle lacks that entirely. These aren't twists, these didn't even feel like loredumps, these just feel like asspulls.
It's kinda sad that these really cool ideas got reduced to asspulls.
