Things You'll Need
Instructions
Obtain a glyph usable by your class and level. Glyphs can often be found for sale at the auction house or crafted by a character skilled in "Inscription."
Open your inventory screen and locate the glyph. Right-click the glyph to learn it.
Press the "N" key on the keyboard, then click the "Glyph" tab on the talent menu.
Click the glyph you want to activate in the right-hand column, then click an empty glyph slot on the left-hand side. The glyph slot you click must be empty and match the glyph type.
Click "Ok" to confirm that you want to activate the glyph. This will activate the glyph in the glyph slot.
