This is the "unlocked" holy grail. A single kill gives 99,999 XP. You can hit level 20 before leaving the first floor.

Purists will argue that using a trainer "ruins" the game. However, there are valid reasons to use the Legend of Grimrock Trainer UNLOCKED-P2P:

A standard UNLOCKED-P2P trainer for Legend of Grimrock typically includes the following hotkey-activated features. Note: Key mappings vary by version, but the logic remains the same.

Leveling is slow in Grimrock. A good trainer lets you add 1,000 or 10,000 EXP to your party with a keypress, allowing you to max out skills like Swords, Armor, or Spellcraft immediately.

Be careful with this one. This cheat allows you to bypass puzzle doors, but it can also break scripted events. It is best used to recover a dropped item that fell into an unreachable pit.

If you don't want to risk third-party software, there are legitimate ways to make Legend of Grimrock easier:

99% of trainers will trigger your antivirus software (Windows Defender, Malwarebytes, etc.). This is because trainers use the same memory injection techniques as malware. However, malicious actors upload fake trainers that are actual cryptominers or info-stealers.

The Rule: Never run a trainer inside a folder that contains your personal documents or passwords. Use a dedicated gaming PC or a virtual machine if you are paranoid.
