Changes to the rules starting with the letter G (Graal and Galtran).

Of course, it's easier to dig up the Grail on Large maps, but it's not that difficult on Huge maps either; it's just that there will be twice as many games where it makes a difference compared to Large maps.
Let me explain again for you and for those who don't understand how to dig up the Grail.

You need two things:
1. An Obelisk
2. Earth Vision (you'll have it almost constantly by the end of day 1, beginning of day 2)

Take a screenshot of Earth Vision, take a screenshot of the map with the Obelisk – and search for your opponent on the fly.

Of course, you need to be willing to do this, but as practice shows, it can be found in 10-20 minutes (even in a not-so-obvious case). And it's not that people don't dig it up on Huge maps because it's difficult or unprofitable (even in the late game, the Grail in a tower is an incredibly powerful advantage and can easily win you the game). It's because it doesn't apply to the heroes we like. And, unlike other objects, you don't have to fight difficult monsters or collect a ton of resources/money to get this bonus.
