DISCUSSIONS on “Rules for online games in HoMM3 and formulas for calculating player rating.”

The prohibition of using the spells Flight, City Portal, Dimensional Gate, as well as the artifact Angel Wings, on the 2sm2c, Balance(200), and skirmish templates at a difficulty of 200% should be implemented with the corresponding resource adjustments. Because, in effect, it introduces a ban on building guilds of levels 4-5. For example, in the last game of this tournament, I get a Town Portal instead of a possible Armageddon, while I changed all the resources to zero. Similarly, why would I need Flight and Dimension Door (or wings in Utopia) instead of the expected explosion? Such a ban introduces a significant imbalance.
Also, let's not forget that in Hillfort, level 1 creatures upgrade for free. And when you have a lot of them (especially if it's a legion of skeletons), it will be incorrect.
For all templates with the computer, remove the rule about breaking through guard passages.

But how do you know if that spell is there or not? Let's say I take an empty Pandora (and it has some magic), or I only get the first two levels, and I don't know if the 4th level was there. In short, maybe I'm not getting something, but the point is unclear and can lead to ambiguities.

I suggest renaming it to "if any of your heroes have learned this spell in Pandora, it can be used by level 4 magic specialists against players." The same applies to Dimension Door, Flight, and Town Portal.

What's not clear here? You use what you have received and understood (and not what you haven't received due to a lack of wisdom) in Pandora.
