Currently I Am playing on normal. So this raider in Lexington has some Power armor and a Fat man I am in my T-45B that has two pieces of blast shielding...I run and start meleeing this guy. I didn't think he would fire the fat man at point blank range but he did...and yet I cut him to pieces with my Boarded Blade and still had 40% HP. Is blast shielding that effective? I know in prior playthroughs suicide bombers with mini nukes one shotted me with T-45B PA on (no blast shielding though).
