Data Xigbar Level 1 Critical Mode (Final Form + Duck Flare strategy PS2)
Ugggghhhhh, this fight is probably one of the most poorly designed fights in this game. Not only does Xigbar fire more rapidly, but his shots now travel far faster than before, leading to many deaths due to inescapable combos from being staggered, due to not having Once More.
The strategy I use here is extremely risky. Xigbar will randomly break out of the Final Form combo I use here, no idea why he does, as sometimes he'll be stuck in it anyway.
Timing Reflect can be very hard, as Xigbar will randomly decide to delay his shots. His attacks are never a set pattern, the best you can do is anticipate his attacks extremely quickly.
This strategy is way easier to pull off in the English versions of 2.5, as Duck Flare is far more powerful in those versions, for some reason.
You can skip his DM, but I have a hard time doing it consistently sadly.
