Part of the Schnee glyphs' versatility comes from Dust.

Just as Blake can create elemental clones using Dust, the Schnees can create special glyphs using Dust.

I say this because the first time we see a Time Dilation glyph, Myrtenaster's blade glows yellow and then fires a yellow beam. That beam hits the ground under Blake, and the Time Dilation glyph forms in that spot.

This implies that a Time Dilation glyph is actually Schnee Semblance + Lightning Dust.
