I tried it with a Golem. I’d been using that for Angels without any problems.
The first time I was going to MJD away so that the supporting ships wouldn’t hit me. I ended up with about 10% structure left after the first hit from the boss. I went into Bastion and spammed the shield booster… Time to leave.
I repaired and did some changes for more EM resist. When I landed in the room I immediately hit Bastion mode. I set auto-repeat for both the shield booster and the bastion. The hard part was searching through the list for the boss, and I ended up taking two blasts from the thing before I started shooting. I got down to about 40% armor with near zero cap left when I ended bastion and was able to limp to a station.
I didn’t try it a third time. The boss and the supporting ships hit you with high EM and thermal damage. I do believe that with some changes to the shields the Golem will tank it. You won’t have enough time for the MJD to spin up, and I’m at MJD level IV. Even level V…you’re going to get at least one blast before it fires.
