As a dedicated offline player and a true SoD enthusiast, I still dare to offer a couple of suggestions.
1. I support the idea of convincing Baratorch to add the ability to connect external modules to the HD mod for playing with non-standard (relative to SoD) rules. And, if he agrees, to develop a kind of compromise set of rules for tournaments, something in between SoD and WT.
2. Instead of shuffling individual spells between schools of magic (which will inevitably confuse true SoD players), you could try to equalize the probabilities of appearance:
1) of elemental magic skills in heroes;
2) of individual spells in the mage guilds of cities.
That is, in SoD we have:
1) some hero classes cannot acquire the skill of magic of certain elements (Barbarians - water magic, Rangers - fire magic);
2) depending on the racial affiliation of the castle, the probability of the appearance of spells of different schools varies.
So, this injustice needs to be eliminated! :) Down with racial prejudices!:smile19: Give water to the Barbarians, etc.!
The only obvious and reasonable restrictions that need to be left are: the inability to acquire necromancy skills by heroes of other races and the non-appearance of "specialized" necromantic spells (wave of death, raising undead) in castles of other races.
Of course, players will strive to acquire some schools of magic earlier than others: first - earth and air, then - fire and water. But at least all heroes (and therefore all players) will be on an equal footing.
