I have never been able to solo a nightfall strike. Most use cheese spots or run past most of the fighting. When I said dodgy spot I only meant a spot where we are relatively safe from ground enemies, we will die a lot thought because of how the spot works.
Gjallarhorn makes things easier for sure, and so do the other good weapons. But I did fine without them for almost a year before getting Gjallarhorn, which will be nerfed soon anyways. We will try it, if we fail then that is how it goes. I can help from like 8 to 9pm, so that is enough time to get it done.
