your questions regarding the game rules (improving the interpretation).

- Allow digging for the Grail on all templates without GO; possibly with a ban on placing it in Conflux and/or Tower.

There is no point in allowing Grail digging only to then restrict it by town. This was discussed about a year ago; I suggested lowering the threshold to 141 (currently 221). But if digging is to be allowed from the start, there should be no town restrictions.

Regarding Jebus Cross and Fly, this question also interests me. About a month ago, there was a game where I needed to fly from one tile of my respawn to another tile of my respawn, but in doing so I would have to fly over a neighboring zone where no passage had been broken through. I did not do this, spent movement points on a detour, and as a result, on the next turn I lacked the movement points to return to town, which caused me to lose the game. I was guided by the following rule -

Transition between zones using the Angel Wings artifact and the Fly and Town Portal spells is allowed:
a) between any of zones 1-4 and the central zone 5, if GO of any passage between the respective zones has been broken;
b) between two zones 1-4, if GO to the central zone 5 and to both of these zones has been broken;
c) in cases of multiple GO of one passage — to approach the GO chosen by the player, with the first action in the new zone being the elimination of that GO.

But the rules do not answer the question: is it allowed to fly over a zone where no passage has been broken, without entering it? The Homunculus situation is essentially about this, not about which tile to hit the GO from. There were several moves over sand there. The whole question is whether this was considered entry. After all, if Dark had taken a slight detour and attacked the GO without flying over the sand, no one would have had any questions for him.

A couple of weeks ago, I saw a similar situation on Lizard's stream in a game against Lawyer (I wanted to take a screenshot now, but both only have water access until July 16, so I couldn't find it). Lizard broke his GO, and the road then slightly extended into the swamp respawn, with the swamp respawn's GO standing on it. At the same time, it was possible to go to the center nearby over the sand. Lizard stated that everything was fine and flew all his heroes along the road over the swamp GO, while the road was located on the swamp respawn. So — was this entry or not?

I formalize the question for all three situations: is flying over a zone without stopping in it considered entry into the zone? It does not matter what the answer is; what matters is that it is unambiguously reflected in the rules.
