Nightmare King Grimm is a Boss in Hollow Knight. Bosses are special Enemies that feature their own arena, a large amount of health, and a variety of unique moves and abilities. You will need to perform multiple attacks such as using The Nail and Nail Arts along with the Spells and Abilities in order to defeat them. Some bosses are capable of entering into a state of stagger after landing a number of attacks on them.

As soon as you encounter a boss, its name will appear on the screen, the music will change into a boss battle theme, and usually,  paths connecting the arena will close or will be blocked leaving you no choice but to face these devastating and unique foes.

Nightmare King Grimm is a final dream boss that was added as part of the Grimm Troupe expansion, appearing the dream version of Troupe Master Grimm (Boss). In the back of his tent, Grimm enters a restless nightmare before being reborn by fire. The Knight must strike him with the Dream Nail and enter his dream in order to battle his dream variant, thus completing the ritual of fiery rebirth. Afterward, Troupe Master Grimm will be reborn as Grimmchild (Stage 4, fully upgraded), and will always be a loyal companion to the Knight.

 

Twisted spectre of scarlet flame.

"The expanse of dream in past was split,
One realm now must stay apart,
Darkest Reaches, beating red,
Terror of sleep. The Nightmare's Heart."
- Seer

    • The grimmchild charm isn't worth this hard fight,carefree melody is also required for all notches. But the main reward is the perfect bossfight you'll encounter. But remember:

      1.close your eyes for 7 seconds when the fight triggers,the visuals will damage your eye. This is serious. Set the effects to low in options.

      2. The soundtrack is perfect but it's bad for your focus on the fight,I recommend to mute it.

      3. only heal when the 4th pillar's base is going red and you aren't on it.

      4.as for charms,quick slash and unbreak STR and mark of pride and steady body. Probaly unbreakable heart or soul catcher or even longnail for the 2 last notches. Listen to me and don't equip quick focus,just go with third tip.

      5.don't use nail arts,I said the reason in the troupe master's page.

      6.lifeblood doesn't transfer into the dream for some reason,don't bother going to howling cliff for 2 blue masks.

      These tips might sound simple,retarded and no-brainer or whatever you call it but they helped me a lot more than any guide.

      • I think nkg is so hard but he is one of my favorite character along with hornet, cloth, pure vessel and of course the knight. On my first run I killed nailsmith by accident. It’s so sad cloth died. I agree with grimmkinwisp on the radiance.

          So annoying how you can’t get the entry by beating him in godhome, because I banished him and I’m regretting it.
