Trekken
Dark Bond
When your Shade is forced to make a saving throw, it uses your saving throw bonus for its roll.
Incorporeal Echo
The Shade has no physical presence, but its space counts as difficult terrain. It cannot use or interact with objects or magic items.
Umbral Guardian
If a creature provokes an opportunity attack from the Shade, you can use your reaction to make an opportunity attack from the Shade's space.
