Specialty Buildings

Specialty Buildings are ways to specialize in any one tower. The buildings decrease the tower in question's cost and upgrades by 5% and buff it in certain ways but increase the cost of another tower and its upgrades by 5%. You must first purchase a plot of land for 250 Monkey Money then you may build a Specialty Building on top of it. You may purchase as many Specialty Buildings as you want then you can activate or deactivate them when you want to but you can only have one active at a time. The first two upgrades increase reduce the price and increase the firerate of the tower. The third upgrade is special and is different for each tower.
