that's a rather complicated strategy for the trio of n00bs. i destroyed them using L4 suicide and demi 3 (really, really dislike the name change for that. gravity/gravira/graviga would be my own preference lol). the hardest part of that entire train section was stealing the armors: the warrior bangle from birdy mclolsauce and the minerva/escort/mystile from the trio. i only managed the warrior bangle and mystile before they bit the dust. curse you steal modifier .
i'm considering retrying it for the other 2 armors, but i'm reluctant to do that drawn out sequence in hopes that all 4 steals happen within the first couple of tries.
That is what I also did but Gjoe's strategy seems like it would be more viable at a lower level or with worse equips, mind you it does involve getting dazers... Which some don't know where to obtain.
Also agreed on the gravity name change. I also dislike the names of quake but, hey , minor quibbles.
