I used the sword of ragnaros or whatever at day 16, used a laser pistol, 3 auto mods equipped, and one of them cup things that make you take no damage temporaraly, yeah worked fine... was mega easy
Some of these weapons are kind of pointless, I just bought the spread shot, saved up for the 4 homing missiles and then bought slow time, no point in buying most guns.
