This bonus only applies if the hero is defending with the army. Other defending troops not under your control will remain unaffected by this bonus. "
This means all troops that are belong to me will receive the def bonus when I sent to reinforce with my hero ?
So, Slovenc was wrong ? :P
My hero have 20% off bonus and 7% def bonus,I train alot Praetorians and Legionaires on other villages, they all will receive the bonus when they're in same village with me hero !!
