Canoptek Spyders

At the beginning of your turn, you can roll a D6 for each Canoptek Scarabs unit from your army that is below its starting number of models and within 6" of any friendly Canoptek Spyders units. On a roll of 1, one of those Canoptek Spyders units within 6" of the unit being rolled for suffers a mortal wound. On a 2+ one of the Canoptek Spyders units within 6" of the unit being rolled for unleashes reinforcements: return a Canoptek Scarab Swarm to the depleted unit, in unit coherency and more than 1" from enemy models. If you cannot do this because there is no room to place the model, do not set it up.
