Autocampaign

Autocampaigns made for IDLE looting.
You hire a hero, hire troops, place troops to the hero's squad and then send the hero to an autocampaign.
You could use an aggressive or cautious stance.
The aggressive stance multiplies loot, but there is a chance, that your hero will die.
The cautious stance prevents losing a hero, but the loot is not plentiful.
The bigger army your hero has, the bigger enemies the hero will fight.
Bigger enemies provide more loot.
So, bigger army - bigger loot.

On the way back the hero will not find enemies and don't have any additional loot.
To make a faster return you should buy and use a towngate scroll.

You could buy it at the blackmarket on the adventure map.
