What your AI companion actually says in Hollow Knight

Hollow Knight is a 2D metroidvania where precision matters more than damage numbers. Sidekick's coaching is tuned around the platforming-plus-combat rhythm — calling parry windows, pogo timing, and charm strategy in the moments you actually need them.

Nightmare King Grimm phase 1:“Pogo the spikes, don't dash through.” The fight that ends most Pantheon attempts becomes manageable once you know the movement language.

Mantis Lords:“You can pogo every downslash — it's safe combat practice.” A teaching callout that helps you build the fundamental skill for later bosses.

White Palace, mid-saw section:“You have Hiveblood — pause on the safe ledge to regen.” Sidekick reads your equipped charms and the room layout together.

Radiance:“Don't commit to attacks before her flash-dash recovery — wait two frames longer.” Frame-tight advice for the final fight.

Five things vision AI notices in Hollow Knight

  • Equipped charms and notch state. Charms are most of your build. The companion knows what you have on and calls out interactions, like Sharp Shadow plus Dashmaster on spike rooms.
  • Soul gauge. The blue meter is your healing and spell fuel. Sidekick coaches when to spend a Focus versus when to push for a Shade Soul.
  • Geo on hand. Some boss strategies want you buying specific charms or maps first. The companion checks your Geo before suggesting a detour.
  • Mask state and Lifeblood.Lifeblood masks are temporary. The companion knows the difference and adjusts risk advice when you're running on borrowed time.
  • Charm interactions you may not have noticed. Quick Slash plus Mark of Pride is a different DPS profile than Quick Slash plus Long Nail. The companion can flag the better fit for a specific boss.

Where Sidekick fits in your Hollow Knight run

Hollow Knight rewards finding things on your own. The companion stays quiet during exploration. Where it shines is in the boss fights, the Pantheons, and the late-game platforming sections where one missed input costs the room. Real-time voice means you keep your hands on the controller and your eyes on the edges of the screen instead of pausing to check a wiki.

What Sidekick will not do

Sidekick won't spoil endings or hint at content past where you've reached. For exhaustive lore, charm notch counts, and 112% completion routes, the Hollow Knight wiki remains excellent. Sidekick is the layer on top — coaching for the moments you're actually playing.
