Myabe you should be able to buy things like a long treadmilland place it somewhere when you make the formation of the troops like the treadmill increase their speed steroids make them stronger and when the goblins get onethey raid more money and magic scroll eancreases aura power of all who passes through. they should not stop working after ONE troop passes through, nor after a wave is completed, though they shoud disappear AFTER the raid. afterwards you should still be able to re-use them after the raid. Plus this comment so the author can see it! :D
