Lower your damage output - Equipping an Extinguished Dragon Key for its flat 75% damage output reduction can help, but you'll usually have to go a little further than that. Good rule of thumb with or without Extinguished (depending on the weapon of course) is to unequip any mods that directly affect base damage, namely Serration, Heavy Caliber, [Primed] Point Blank, Hornet Strike, Magnum Force, [Primed] Pressure Point, and Spoiled Strike. On the flip side, you can also slot ONLY those base damage mods in instead. Do to same to your sentinel weapons (if you leave their attack precepts on) and/or companions (Maul).
