Learn to Parry
As you progress further in the game, you’ll encounter more and more enemies with ranged attacks. To counter this, it might be useful for you to consider picking up the Reflexes ability. While Corvo and Emily can parry regular attacks, Reflexes will allow you to parry ranged attacks.
Later on, learning to parry can evolve from a defensive tactic to a much more offensive one. The Superior Deflect upgrade will let you actually deflect bullets and bolts, and use them to hit nearby enemies. This will help to clear out mobs much faster, and allows you to refrain from taking damage, while simultaneously attacking foes at the same time. The Snap Reaction upgrade is also useful in that it slows down time whenever you’re spotted by enemies, giving you time to react and counterattack.
