Diablo 4’s endgame players can unlock major bonuses by equipping the right Glyphs. These game-changers are crucial for max-level characters and offer a competitive edge.
However, getting started with Glyphs requires some planning, as they become available only after reaching the max level. Once there, players must upgrade their Glyphs to scale into Torment difficulty. The process is straightforward: complete Pit of the Artificer runs to earn attempts at upgrading Glyphs.
The number of upgrades depends on the run’s completion and your personal power level. Faster clear times grant more opportunities for upgrading low-level Glyphs. Players should aim to optimize their builds for better performance.
To understand how Glyphs work, consider them as bonus inserts in Paragon Boards. Each has a main and secondary effect: the former typically scales with stat nodes within its range, while the latter requires a specific number of nodes.
By placing Glyphs on suitable boards that fulfill their requirements, players can unlock more flexibility. Leveling up to 15 and 45 expands their ranges, making them viable across multiple Paragon Boards.
