Unity Tendril, Mk 1

Biotech

A green tendril emerges from the back of your neck. You can retract or extend it as a move action. It’s not prehensile, but you can use a standard action to touch it to another willing creature and connect your minds. Your tentacle remains in contact with this creature until they’re no longer in your reach or you use a move action to detach the tentacle. During contact, you and the target can communicate with each other as if you both had telepathy. When you and the target are connected by the tendril, you both automatically succeed at attempts to aid another and provide covering fire, but only when doing so for each other.

A Mk 1 Unity Tendril has a reach of 5 ft.
