I was reading the queensland barracks prizes thread and I have cement factory level 10 to reduce upgrade prices but what are upgrade modifiers? What other reduction cost there is besides the cement factory?

Sometimes prizes from WD events may provide an additional reduction in building and/or upgrade costs in addition to the cement factory. I have an additional 2% from the war on Poland.

Certain boost units provide a discount in building upgrades. An example is the ANZAC Bridgin unit. It is the top 250 reward for the battle of Australia and provides 5% upgrade cost. Hope this helps.
