Glyphs

Glyphs are a gameplay feature of Diablo IV. They are items found throughout Sanctuary that, when embedded into a Paragon Board, confer various benefits based upon the number of active tiles within their radius.

Glyphs can also be leveled up by delving into some particularly dangerous dungeons. Leveling up a Glyph extends the radius of their effect, allowing each one to draw power from or impart power to even more active tiles.
