It seems all Lagrangian abilities as well as the AG3 ability were set to damages which assumed single application of the damage. The vanilla beam blast ability these are derived from doesn't work like this, instead it applies damage per time interval and infinitely during the beam duration. All beams seem to use 1 second as the time interval and so these beams do a huge amount of damage. The Lagrangian Beam on highest level will do 90000 * 11, so 990000 damage. It's unlikely that this was intentional since there's no ship that comes even close to such shield/hull values so all these abilities will be recalculated (damage value divided by duration then result applied as new damage).
