IIRC I can't equip stuff yet, will dig around in the menus a bit.
Oh are you talking about the first Devastator fight really early in the level? He has way less aggressive attacks at that point iirc. Just his swing and smash, Sometimes he takes out his gun but that's easy to avoid as long as you're on the move. Main thing is to focus on his head as much as you can if you want to maximize damage, but if you want to stick behind him and dodge between his legs to slowly wear him down, that works too.
Best advice is: Don't look at his health meter when fighting. It's a huge psychological deterrent. If you just focus on fighting him, it'll be over before you know it.
