As we reached legate I whipped out my riot shotgun and started to go to town on him not making a dent. Then the next thing I know I hear the *BOOM* of my anti-material rifle coming from Boone. Well the svcker did 20% damage to Legate in that one hit causing him to run away like a freaking coward. I followed after him pelting him in the [censored] like kids going after the odd ball in gym class. Managed to nuke him a bit before Legate's friends came out to assist in the battle. Took some doing, but managed to kill his friends with some diligence and a hefty amount of stims. This is when Legate returned to try to finish the job, but Boone pelted him again with the AM rifle loaded with AP rounds.
Seems that Boone maybe the best person to take care of Legate loaded down with the Anti-material rifle and AP rounds. However this was probably due to me picking up Boone in the beginning when I was level 13 to 15. He had 305 Health and probably did a ton of damage since he could nearly 1 shot death claws with the 308 sniper rifle.
