Didn't know about this devastator farm thanks

Just got my ammo regen ogre but it's 75% fire rate and not revenge :/ Edit I have like 15k hours in this game this is counting my saves from ps3 ps5(ps4 version) only I also have saves on my pc and nintendo switch lol I've played this game far too much to be farming Ajax ogre for what feels like my 10th time and haven't even seen one drop yet.. But got a good pearl ogre from the gift shop 400+ damage and 90 ac with 12.5 rof for my explosive brick
