# How to clip a gap between a word and its “shadow”

I want to achive a text effect like this:

It is the "gap" between the word and the shadow.

I understand I have to use two layers to create shadow and word. But I don't know how to clip the shadow layer (adding a layer between word and shadow using white wouldn't help if using a background image.)

This is, how I would create the "word-layer" and the "shadow-layer":

\documentclass[12pt]{article}
\usepackage{tikz}
\usepackage{fontspec}
\begin{document}
\begin{tikzpicture}[remember picture, overlay]
\node [inner sep=0pt, xshift=0.78cm, yshift=7.48cm, anchor=south] at (current page.center) {\fontspec{Arial Bold}\color{gray}Effect};
%A "clipping layer" here
\node [inner sep=0pt, xshift=0.8cm, yshift=7.5cm,  anchor=south] at (current page.center) {\fontspec{Arial Bold}\color{black}Effect};
\end{tikzpicture}
\end{document}


Could anyone help with the clipping part?
