Flip on Infinite Health and your masks simply never break, so you can learn a boss pattern in peace, sightsee through hazard rooms, or bulldoze the Radiance on your fifth try.

</>Common questions about Unkillable (Infinite Health)
What does Unkillable do in Hollow Knight?
Unkillable keeps you alive in Hollow Knight no matter what Hallownest throws at you. With Infinite Health switched on, your masks simply never break, so bosses, spikes, and bottomless pits stop being able to end your run. Some fights in Hollow Knight demand pixel-perfect dodging; this one asks for nothing, letting you learn a boss pattern in peace, sightsee through hazard rooms, or bulldoze the Radiance on your fifth try. There's also an Infinite Soul switch so you always have enough to heal and rain spells without hunting for a bench. Both switches work independently. Unkillable is a free mod from ProjectMods, the community-first game modding platform, and toggling it off restores normal health and Soul instantly with nothing changed on your save.
What's the difference between Unkillable's Infinite Health and Infinite Soul in Hollow Knight?
Unkillable gives you two separate switches in Hollow Knight. Infinite Health keeps your masks full so you can't be killed, no matter how many hits you take from bosses, spikes, or pits. Infinite Soul keeps your Soul meter topped up, so you always have enough to Focus and heal or to cast spells like Vengeful Spirit without hunting down a bench to refill. They cover different problems, one is about not dying, the other is about never running dry on Soul. The key detail is that they work independently, so you can turn on just one or both depending on the run you want. Unkillable is a free mod from ProjectMods, and each switch takes effect immediately when you flip it.
Can I use Unkillable's two switches independently in Hollow Knight?
Yes, and that flexibility is one of the best things about it. Unkillable's Infinite Health and Infinite Soul toggles in Hollow Knight are fully independent, so you can mix them however suits your run. Leave Infinite Health off and Infinite Soul on to stay squishy but spell-happy, casting freely while still risking death, a fun middle ground for spell-focused play. Flip it the other way for tanky but Soul-starved, unkillable in a fight but still managing your Soul the honest way. Or switch both on to remove every threat at once. It's your call each session. Unkillable is a free mod from ProjectMods, the community-first modding platform, and because the two switches don't depend on each other, you can change your setup any time mid-run.
Does Unkillable work against bosses like the Radiance in Hollow Knight?
Yes. Unkillable's Infinite Health applies against every boss in Hollow Knight, including the toughest ones like the Radiance and the Pantheon gauntlets, because it stops your masks from breaking at all. That means a boss can land every hit and you'll still be standing, which turns a wall you've been stuck on into a fight you can actually study. Use it to learn an attack pattern in peace, to push through a boss rush that keeps resetting you, or just to finally see an ending you've been chasing. Add Infinite Soul and you can heal and spam spells throughout too. Unkillable is a free mod from ProjectMods, and switching it off returns every boss to dealing normal damage, so your save is never permanently softened.
How does Unkillable pair with other Hollow Knight mods from ProjectMods?
Unkillable is a great base layer for a stress-free Hollow Knight run and pairs naturally with other ProjectMods mods. Combine it with BOOM HeadShot! and you become a walking full stop, unkillable while every hit you land is an instant kill, ideal for bulldozing a boss rush. Pair it with Sky Walker's infinite jumps to explore hazard-heavy areas without worrying about spike pits or bad landings. Or run it alongside Shield if you'd rather hits not register at all rather than just soaking them. Each mod toggles independently, so you decide exactly how much of the challenge stays in. All of them are free mods from ProjectMods, the community-first game modding platform, so you can build the exact run you're in the mood for.
