About Library Of Ruina
Library of Ruina is a strategy RPG developed by ProjectMoon that centers on tactical battles set within a mysterious library. Combat unfolds like a staged performance where guests and librarians face off, and those who fall become part of the growing collection of books. The game challenges players to manage these encounters carefully as they expand the library’s holdings.
The progression revolves around acquiring new books created from defeated guests, deepening both the story and gameplay layers. This ongoing accumulation eventually leads to uncovering a unique, ultimate book at the heart of the library. The single-player experience combines strategic combat with an intriguing narrative framework.

Antivirus False Positive Notice
This trainer uses memory-editing technology to modify game values in real time. Some antivirus programs may flag it as suspicious — this is a known false positive common to all memory-editing software, not an indication of malware.
Verify the file yourself: Upload it to VirusTotal.com to scan with 70+ antivirus engines before running.
How to Install the Library Of Ruina Trainer
- Download the trainer archive from this page (button above).
- Extract with WinRAR or 7-Zip — password if any is shown beside the download.
- Disable real-time antivirus only if a false positive blocks extraction. Trainers modify game memory; many AVs flag this as a generic heuristic. The included VirusTotal scan is your sanity check.
- Launch the game first, reach the main menu, then start the trainer as Administrator.
- Use the listed function keys (F1–F12) to toggle each cheat — health, stamina, money, ammo, instant skill cooldown and so on.
Compatibility & Anti-Cheat
Library Of Ruina trainer targets the single-player and offline modes on the exact game build noted at the top of this page. It is not designed for online or multiplayer play and should never be used with Easy Anti-Cheat, BattlEye, FairFight, or VAC-protected lobbies — running a trainer there can result in a permanent ban from the game's matchmaking servers.
Troubleshooting
If the trainer hotkeys don't activate: confirm the game version above matches your installed copy (Steam → game properties → Updates), install the latest Visual C++ Redistributables, and verify your antivirus hasn't quarantined the executable. After a game update, check this page for an updated trainer build before reporting a problem.
FLiNG has authored free PC game trainers since 2010. All trainers on this site are submitted by the FLiNG team or community contributors and verified before publication.
Library Of Ruina Trainer Highlights
The free Library Of Ruina trainer for ProjectMoon's game adds single-player cheats such as Infinite HP, Infinite Stagger Resist and Infinite Light. It runs offline, is kept in sync with the latest game build, and every option is toggled with its own hotkey inside the trainer.
Pro Tips from the Editor
- Mega EXP early snowballs your build — pair it with Max Gold for gear.
- No Skill Cooldown turns boss fights into a rotation test, not a waiting game.
- Keep Unlimited HP/MP off for story bosses if you want the challenge.
Library Of Ruina Trainer — FAQ
Is the Library Of Ruina trainer safe?
Yes for single-player use. It edits game memory at runtime; some antivirus engines flag memory editors as a generic false positive — scan the file yourself before running.
Does it still work after a Library Of Ruina update?
Game patches can shift memory offsets and break older builds. Check the version at the top of this page; refreshed builds are posted after major patches.
Will I get banned for using it?
Use it only in single-player/offline. Never run a trainer in online or multiplayer modes — anti-cheat can detect it and ban your account.
