In Evony, just like troops, there are instant build fortifications with heroes that have a high politics level.

Yes, it’s insane!

Having insta-Traps and/or insta-Abatis is great for defense. Having insta-Trebuchet is nice for dropping honor and leveling heroes..

Here are the politics levels required with and without Wealth of Nations to instantly build wall fortifications.
