Outcast's Path

Veteran. Unfortunately, I don't have a castle – I visited the elves, and they sent me away... so I went to the arenas and headed towards the orcs. I don't know where the portal to the castle is.

It will be tough on the veteran difficulty. There is a portal in the southwest that leads to your "home" castle. You can replenish your forces there.

If the yellow player doesn't attack on their own, it's better not to rush to kill them. In about 20-25 days after their death, they will reappear with an even larger army, but not much larger.
