My Lands: Black Gem Hunting

why is it a hero can not seize an empty outer domain? all the wiki says is a hero will lose a battle without troops because he/she has no attack parameter but a carrier can seize an outer domain and they do not have attack value either. seems to me a hero should be able to seize a domain as well

Carriers have 0 attack value, 0 is a number also parameter, that is why carriers are able to seize an outer domain alone but heroes can not.

well if that is the reasoning then to me it's just another shifty aspect to this game. zero is zero whether it is implied, as for a hero, or actually shown as with a carrier

Heroes do not expect the army at the beginning of the war. Or strengthen a spell, but never the war.
