</>Common questions about Immortal Slugcat
What does Immortal Slugcat do in Rain World?
Immortal Slugcat makes your slugcat completely untouchable in Rain World — while it is on, nothing in the world can kill you. A lizard's jaws, a fall from the very top of the map, a lungful of water, or a full flood cycle all leave your slugcat perfectly fine. It is the stress-free way to learn a dangerous region, line up a tricky shortcut, or simply wander somewhere terrifying and enjoy the view without a run-ending death. Immortal Slugcat is a free-tier mod from ProjectMods, and it is fully reversible — turn it off any time to put every danger in the game straight back.
Which kinds of death does Immortal Slugcat protect against?
Immortal Slugcat covers the full spread of ways Rain World normally kills you. Predator attacks — lizards, vultures and worse — stop landing fatal blows. Fall damage disappears, so a plunge from the top of a room does no harm. Drowning is handled too, so running out of air underwater no longer ends you. Even the rising water and the deadly flood at the end of a cycle leave your slugcat untouched. Because it is a single master switch rather than a stack of separate protections, you do not have to think about which hazard is coming next. It is a free-tier mod from ProjectMods.
Does the deadly rain still kill me with Immortal Slugcat on?
No — with Immortal Slugcat active, even Rain World's signature killer downpour and the flood that fills a region can't take your slugcat down. Normally the arrival of the rain is a hard countdown to death, and being caught out in it ends the run instantly. This mod makes your slugcat untouchable across the board, so the water and the storm pass over you harmlessly and you can keep exploring right through what would usually be a wipe. It does not stop the clock or hold the rain back — the weather still happens — it simply stops it from hurting you. Immortal Slugcat is a free-tier mod from ProjectMods.
What does the Invincible toggle do?
Invincible is the single master switch behind Immortal Slugcat in Rain World. While it is on, every source of death in the game is switched off for your slugcat at once — there are no separate sliders or per-hazard options to manage. Flip it on for a run where you simply cannot die, and flip it off to return your slugcat to fragile, normal vulnerability. Because it is one clean toggle in the ProjectMods launcher, you can switch between a safe exploring session and a genuine survival run without any fiddly setup. Toggling it is reversible and does not damage your save, so the danger is always one click away when you want it back.
Why would I use Immortal Slugcat in Rain World?
Immortal Slugcat is for when Rain World's punishing difficulty stands between you and something you want to do. Use it to learn the geography of a lethal region without restarting constantly, to practise a hard shortcut until it is muscle memory, or to sightsee in areas that are almost impossible to survive normally. It is a favourite for content creators who want to show off the world calmly on camera, and for newer players easing into a famously brutal game. As a free-tier mod from ProjectMods, it is completely reversible, so you can flip on invincibility for the parts that frustrate you and switch it off the moment you want Rain World's real tension back.
What options does Immortal Slugcat include?
