I actually just got finished farming the ash blue prints, now to wait three days.
Is his teleport move still broken?
I'll note that having a Rhino makes bossfights like the Jackal so much faster/easier, though. Maybe I'll try a Rhino speedrun on Jackal later today and see how quickly I can do it.
How long does it take to gather up the parts for Rhino?
I remember having to farm War 30+ times for Mag parts and it ended up taking about an hour or two since I kept getting the chassis.
I am currently gathering parts for Rhino and it takes quite a long while to gather up all of them. Especially Rubedo for helmet and chassis. You need a total of 500 and you get like 10-50 on each run. Also, it's a total of 70k credits in all the building process.
