Flee the Scene

Prerequisite: 5th level, Pact of the Key feature
When you teleport, an illusory double of you appears where you were standing. The double disappears at the beginning of your next turn or when it would take damage. Your double acts naturally, though it cannot speak, gesture, or move from the space it originated in.
Additionally, your range of your teleport increases by a distance equal to half your movement speed.
