NHF – new heroes for Heroes V 3.1.

I didn't come up with a hero, but here's a special one: Name: Architect Description: Every week, the hero can build a barracks or an archer tower (randomly). Construction takes 4 days, and they don't work on Saturdays and Sundays.

And here: Name: Warlord Description: Zealots and Footmen arrive randomly each week; the count depends on the hero's level.
