The Knight GOLEM is a very dangerous ANMC and one of the most dangerous GOLEMs that Aya will fight. It is quite a different beast than the others that have fought up until this point. Their first attack is to grab Aya from behind: if she manages to break free they inject her with a toxin which inflicts Poison, but if she fails they brutally snap her neck. If Aya survives they will then turn invisible, becoming immune to every damage while in this form.
The easiest way of fighting them is to stay with your back near a wall, in order to prevent a backstab. Frequently they will create a hologram identical to the real Knight, but the hologram stand still and doesn't attack: do NOT run through this as the real one will appear to attack Aya. The real one appears because it has a faint shadow and a buzzing sound can be heard. It will quickly cloak but the attacks should do enough damage to prevent it from attacking.
When it is going to charge Aya, a laser sight becomes visible. By avoiding this, Aya can also get some damage in there.
