I went through the initial stages of the vamp event with some trial and error, but now SE-8 is giving me trouble.
I can get the lower bomb to its destination 100% of the time, but the the next two are way more difficult. I either get overwhelmed on top, where Yu and the healers go down after enough fireballs or the attack goes somewhat smoothly, yet still tapers off before reaching the goal.
My squad is mostly the same as last time, though I put in some effort to level Amiya to 70.
