Iron armor should reduce the damage from truck to manageable, if you're willing to use /killall to put them down, i don't think you'd snub at the key bypass to get iron armor.

I don't go after bone mass till I have the frostner just because I dislike the fight that much. Its not the difficulty, its the environment.
