Tournament on the 2SM4d(3) map.

If you get lucky with the resources, there's no time or need to dig. ;)

Besides the Grail, there are guards along the roads and passages through adjacent and treacherous territories, where opponents are also often encountered.
Here, unlike the mini-nodes, you can quickly reach an opponent without needing control.

What does the possibility of a random encounter with an opponent have to do with it? The idea that eventually EVERYONE will dig for the Grail, gaining skills, is about 2 heroes digging near their main base (for 2-4 days) and getting a ton of bonuses, from all the magic to just 5k income and a 50% troop growth. Who said that a digger is at a disadvantage in terms of troop strength and that an opponent will come to them? Going to an opponent without control means you're going across a virtually barren land and into the unknown?

The template is already fun. Why add fuel to the fire by digging for the Grail?
