Shield disruption sectors

[PvK]

Is the effect of terrain shield disruption (abilities.txt/"Sector - Shield Disruption") just like a shield damage only hit, or does it reduce the maximum shield level of each unit?

If the former, is it just once at the beginning of a battle, or does the hit take place each turn?

It reduces the maximum value. A negative ability increases the maximum value.

Ah, very nice, thanks!
