New exotic sword idea

Exotic Sword: The MindFlayer
A wicked blade that can transport you and enemies to the mindscape.
Quote: “I will crush the life out of you, false world or no”
Psionic Projection Ability: can transport you and nearby foes to the mindscape but if you kill them they stay dead but if they kill you it simply dissolves the mindscape and you still live.
10 minute cooldown after use of the transport ability.
