The ninth stage of the Kanigem Tournaments

Or perhaps it's not more interesting; what's the point of using all sorts of bugs and loopholes?! Shall we just call the tournament "Who can cheat better"? There are many bugs in the game, that is certainly true, and not all of them are written in the rules, but if we allow even those that are...
This isn't game depth, it's a flaw and a headache for the organizers...

For example, on other resources besides Gugolka, no one has found it acceptable to allow pulling a grave from under monsters; they consider it a bug, a loophole, or cheating. So now, we have to constantly look at others, even if we can make the game more interesting. Why more interesting?
Option without the grave: You solve all the Grail puzzles, send a unit to dig it up, and pass the excavated Grail along a chain back to the Fortress.
Option with the grave: Solve the puzzles, set up the chain, kill a hero on something, pass the grave along the chain, dig up the Grail, and then pass both the grave and the Grail back to the Fortress via the chain.
Which has more facets? Which option? Which requires a more precise calculation of moves and where is the combination more elegant?

Regarding the matter of using the grave to eat crystals, here is what I'll say. If the grave cannot be upgraded using crystals, then speed-running pro players won't be distracted by crystals at all, as they wouldn't waste precious hero moves unless a crystal happened to be right in their face along the way. In the end, their poorly upgraded hero will still win long and tedious battles; it will just take more real-time. And if you, Luchik, give this phenomenon some sort of realistic-objective interpretation, such as the grave being unable to learn, then I will give you a different explanation:
A unit carries the grave for resurrection, visits haste spots and collects crystals along the way :) and places them on the hero (decorates the corpse). After resurrection, nothing stops the hero from eating those crystals.

Well, in any case, if you disagree—far be it from me to stop you. The main thing is that the rules of the current tournament will apply to all players. Everyone is on equal footing. But in my opinion, this was allowed during the 4th stage of Kanigem. Although there was a different organizer back then.

Therefore, all other "grave techniques" are FORBIDDEN.

Firstly, this statement of yours is not in the rules. Secondly, it contradicts rule point 8)
---------------
8) EVERYTHING ELSE IS PERMITTED.
(an unlimited number of heroes on the map beyond eight, and so on).
---------------
And you surely don't know all the tricks of grave technologies, nor do I, for that matter. For example, nothing stops me from packing more than 8 heroes into graves, and this is permitted. A grave is not considered an active unit on the map. Then I can carefully scatter the graves along the Fortress gates and begin resurrecting them one by one. In this way, I can block the gates of certain Fortresses so that one specific hero can escape to another desired Fortress. At this moment, there may be more than 8 active units/heroes on the map—this is exactly what is written in point 8: having an unlimited number of heroes on the map beyond 8, and so on. Perhaps you misinterpreted this point, but I know for sure that Zveroboy meant exactly THIS in his rules! And that also involves the use of grave technologies. Therefore, it is wrong to write in your posts that all other "grave techniques" are FORBIDDEN. Because such a statement, as I wrote above, contradicts p.8) EVERYTHING ELSE IS PERMITTED.

I want to thank IronAxe for their vigilance, although I of course noticed this unpleasantness a little bit earlier, but..
In any case, I won't make excuses again. I take full responsibility for this unpleasantness!

Well, alright. Nothing terrible has happened yet. Now, if we had all realized this halfway through the tournament—then yes—it would have been a real mess.
