Some enemies possess very strong attacks that do a lot of damage if they hit you.However, such attacks can be avoided before they hit home. These enemies usually indicate their intention to use a lethal strike with some warning sign, both visually and audibly. When you see such a sign, quickly get out of the creature’s way.
Note that enemy attacks in general can be avoided if you time your movement right – and if your character is fast enough. This is true even for ranged attacks. You can dodge everything except for the fastest moving projectiles.
