Hejiro, ol boy, when your Engie gets to about lvl 120-130+, you will be able to aquire a nano that turns yourself into one of those Slayerdroids we see, all white and shiny
One thing to consider; while you are in that robotic state, your attacks base themselves on your MA skills it seems. Try to get ahold of an experienced Engie, and ask about that. Try to look for Hamilton or Jica, and tell them you are a friend of mine, and ask. Hopefully they will be able to expand on how that works. Or, simply try to ask any high level Engie you come across, I can recommend the Tir grid area, always lots of high levels there.
