Create Editable Text Hard Long Shadow in Adobe Illustrator

Blend and Offset Path both soften the edge or force an outline. This method builds the shadow with a Transform-driven copy in Appearance, so the shadow angle and length are numeric and the text remains text.

The advantage

Because the shadow is a transformed duplicate rather than expanded geometry, you can change the direction by editing one number. The edge stays hard, the file stays light, and the word can still be retyped.
