New Gamma World
You may ignore any movement restrictions caused by webbing. As an action you may produce 20 feet of webbing. As part of that action, you may use the webbing to set a trap in an adjacent space. Any creature who enters the webbing stops their movement in that space and cannot take the Dash action this turn.
You may also use this webbing as rope. The webbing decays after 2 hours. You must finish a long rest before you can use this mutation again.
