How to Solve the Cemetery Headstones & Grave Lock
1. Examining the Headstones: Scattered across the cemetery are multiple headstones. Each tombstone is inscribed with an individual's name, a carved mystical symbol, and their birth and death years (e.g., 1842 - 1864).
2. Calculating Lifespans: Subtract the birth year from the death year on each headstone to calculate how many years each person lived.
3. Identifying the 3 Shortest Lifespans: Compare all ages and find the three individuals who died at the youngest ages (shortest lifespans). Note their corresponding symbols in ascending order.
4. Entering the Grave Lock: Walk to the central mausoleum where the Grave Lock tumbler is located. Input the symbols in order from shortest lived to third-shortest. The lock clicks open, revealing the relic and unlocking the Festering Felix head accessory plus Biter Fedora.
