I could make a few more jokes about this Trainias unfortunate name but i think the thumbnail is about as much as i should probably do.
Whats there to even say about Malechroid? Its Bujin but with 2 wings and it can hip check you as if it were a plesioth. Typically staying in front of malechroid at all times can prevent it from doing dumb stuff. Ideally you just want it to use its attack where it scratches you with it talons. Malechroid can easilly get stuck in a loop of this for a very long time which is what you want.
SB gameplay is extremely brainidead on this fight. Its basically just Pheasant opener into Harrier BAP spam. You can do a bit more and use FW when malechroid is downed but i feel like thats a time loss instead of a gain to get jolt off CD, this fights just too short. Pinion landing a crit is important too since you only get 1 for this whole fight. These Alters trainia are extremely short so every movement matters. I unfortunately miss-timed a early BAP and Tri-shield took the blow for me so that could of been sub 1min had i not messed up there.
I was debating just doing this until i got sub 1min which with some better crit rolls and enemy ai i could easily get BUT I'm actually quite busy this week and so ill just upload this 1min run and slowly chip away in my spare time.
This is a easy boss. Its just enemy AI and crits here so aside from some very minor optimization there's really not much going on. What you see is what you get with this boss.
