Make veng an activatable module
Upon activation, incoming damage ignores shield
For the next few seconds, every point of damage taken by the hull adds x points of damage into a buffer
At the end of the activation period, shields start taking damage normally and the damage buffer is applied as area damage around the ship
Downsides are that Andreas will have to change the lone battleship ai
Mirror shield is very similar to this mod, imo it should be changed to old mirror shield which applied direct damage
