Intensify Point-Defence

All Ships with this rule in a Group combine their X values into a single value, Y.
Friendly Groups in coherency within 6” of a Ship with this rule and the same Orbital Layer (including its own Group) gain the benefits of Aegis.
When rolling saves against Close Action and Bomber (of any type) attacks, those Groups gain Y additional save dice they may add to those saves. Before rolling to save, the defending player assigns these dice against specific weapons, divided up as they choose (including any modified hits).
An Aegis Group can only grant the benefits of Aegis once each time a friendly group is attacked.
A friendly Group can only benefit from Aegis from one Group each time it is attacked.
