</>Common questions about Nine Lives (Unkillable)
What does Nine Lives do in Sephiria?
Nine Lives makes you take zero damage from everything in Sephiria. Traps, boss attacks, big scary explosions, unlucky rooms — none of it moves your health bar while the mod is on. That turns the dungeon from a place that can end your run at any moment into a stress-free space you can explore, experiment in, and learn at your own pace. It doesn't change how you deal damage or clear rooms; it only stops incoming damage from touching you. There's also an option to extend the same protection to your co-op partners while you host. Nine Lives is a free mod from ProjectMods, and you can turn it off any time to put the danger right back where it was.
What does Protect Co-op Partners do?
Protect Co-op Partners is an optional toggle that stretches Nine Lives' damage shield over your teammates in Sephiria — but only while you're the one hosting the online session. With it on, everyone in your co-op run shrugs off damage the same way you do, so the whole group can push through a nasty floor together without anyone going down. With it off, the shield covers just you and your partners play by the normal rules. It's perfect for carrying a friend who's new to the game, running a relaxed co-op session, or tackling a brutal boss as a team without the wipe risk. Because it's host-side, make sure you're hosting for it to cover the others.
Does Nine Lives protect against traps and environmental damage too, or just enemies?
Nine Lives covers everything that can hurt you in Sephiria, not just enemy attacks. Spike traps, hazard tiles, environmental explosions, boss slams, projectiles — if it would normally chip your health, it does nothing while the mod is on. There's no category of damage that sneaks through; your health bar simply stays put. That's what makes it so useful for exploring dangerous rooms and testing risky routes, since the usual one-wrong-step-and-you're-dead tension is gone. Keep in mind it's purely defensive: it stops damage coming in but doesn't make you hit harder or move faster. For that, you'd pair it with something like Overkill. On its own, Nine Lives is your all-purpose safety net.
What do the two toggles in Nine Lives control?
Nine Lives has two toggles in Sephiria. The Enabled switch is the master control — turn it on to shrug off all damage, turn it off to go back to vanilla and let hits land normally again. The second, Protect Co-op Partners, only matters in online play: switch it on while you're hosting and your teammates get the same damage immunity you have. Leave that one off and the shield stays personal to you. So a solo player just uses Enabled, while a host who wants to protect the whole squad flips both on. Both are instant and reversible, so you can drop the safety net whenever you want the challenge back.
Why would I use Nine Lives — doesn't it remove the challenge?
Nine Lives is about choosing when the challenge applies in Sephiria, not deleting it forever. Plenty of players flip it on for a specific reason: to learn a brutal boss's full attack pattern without dying and restarting, to push deep into Hard Mode floors just to see what's down there, or to give a nervous co-op partner a relaxed, pressure-free run. Content creators and streamers love it too, since it lets you show off a level or answer chat questions without a surprise death cutting things short. And because it's a simple toggle, the danger is only ever one click away — turn it off and Sephiria hits just as hard as it always did.
