0* Crow, 1* Nemesis, 1* King
Jetpack/Grappling Hook/Missiles
This was not a straight run, there were a lot of failures (Stage 2 in particular) cut out. Most of the difficulty is frontloaded. The most difficult stages are the first four at this low CS. Picking up time is necessary in the beginning stages where your DPS is garbage. You will need to abuse Crow jetpack and Nemesis neutral dodge slow field an absurd amount. If you are really cheesy you can reload stages and use jetpack/grappling hook to look for free blues, I get lucky on a lot of stages but I didn't really reload looking for them, I just reloaded stage if I died.
On buffs:
An elite is worth 25%, so 4 elites will end a stage. That means you should be getting 4 buffs minimum per stage. However, free blue buffs will sometimes spawn in the level, hence why I use grappling hook along with jetpack to search for these quickly. Sometimes you get unlucky and cannot find elites.
You want to go for damage boost on kill and main DPS elemental damage (volt), the former is a way to scale up besides relying on elites/random blues. Once you get to 4 stacks of the first you can start killing random mobs in addition to 4 elites per stage. A note when you clear a stage, all mobs in range will die and drop their item, this means if you're at 75% and two elites are near you, killing one will clear the stage and get you both their drops. This also means that if you kill a low level mob to clear a stage next to an elite, you get the elite's drop for minimal effort, something I could have done on stage 7 but forgot to.
Despite having a 3* Samir, I don't think she would have let me cheese the stages as hard as Crow does, I use her for Bygone mainly. (no jetpack cheese :V)
