Shocker

Shockers are stationary enemies found in the Ossuary (all difficulties) Corrupted Prison and Forgotten Sepulcher (only on Normal difficulty). They attack with a large area-of-effect shock wave.

Behaviour
Shockers are completely immobile, but if they see the player on the same platform and within attack range, they will charge up and generate a damaging aura around them.

Shockers resist Poison and Bleeding.

Strategy
If you see a Shocker out in the open, they can easily be killed out of reach with a ranged weapon. If the Shocker is in a confined area, you will need to exercise more caution against them.

It's best to kill a Shocker with burst before it can attack. Most weapons should be able to kill them quickly but if you're not dealing enough damage, then you might need to use your cooldown skills. Carrying a burst damage skill is recommended for the area. Slow effects like Melee are also effective against them, giving you more time to hit them before they charge up.

If you can't kill a Shocker fast enough, then hit it a few times and retreat outside of their radius before you can try again. There is a fairly lengthy delay before they start charging up again.

Since Shockers are immobile and can't chase you, they should always be dealt with solo after you've taken care of other nearby enemies.

Since they are immune to Poison and Bleeding damage, weapons like Alchemic Carbine or Throwing Knife are ineffective against them. They also don't have a front or back, so Vorpan and Assassin's Dagger are also weaker against them.
