Hero from friends city
ok. I thought if a hero got slain the next day or later on in that day I can revisit my friends city and if there is a "HERO" icon in circle above the hall of hero and if I click on it, I should gain a hero. so I got a hero REVIVED. After all if I click on my friends city and I find the hero icon above their hall of hero's it says "+1 hero" which mean I just gained a hero. Right?.
if not what does this mean?.. I know I can go back and get ambrosia but if I spend the time going threw all my friends list and clicking the hero icon above their hall of heros and it says "+1 hero" I should get a hero back then ican use the ambrosia to summon the rest back right?.
If NO then what is the point of the icon above the hero and when clicked on it says "+1 hero" ?
