Wooden fortress Springald benifits from Roller Shutter Triggers

So if you have the Roller Shutter Triggers upgrade. And have a Wooden fortress then put a Springald Emplacement then put another emplacement.

Your Springald attack will be 11 range. Does not benifit from the attack speed bonus.

Important thing to reproduce this is to put another emplacement after the Springald Emplacement.
