- Remove the 25% hit bonus for monster specialists.

Definitely a plus.

- Remove classes as a concept and transfer their functionality to individual skills.

Warrior, Sage, Explorer, and Governor should be removed completely. Speedy -> Navigation Terraformer -> Pathfinding (prices need to be adjusted, should be increased) Healer -> First Aid (also casts spells based on skill level) Leprechaun -> Luck Marauder -> Leadership (numbers need to be reduced) Merchant -> Estates (numbers need to be adjusted) Artificer -> Eagle Eye (conditions need to be discussed)

Seems like a good idea, but Speedy should be reduced by about 30%.
- Diplomacy - reduces the cost of monetary transactions with the Merchant and Terraformer, increases the maximum purchase volume from the Merchant. Numbers need to be adjusted. Also, on the advanced difficulty level, it allows you to bribe neutrals, and on the expert level, it allows you to bribe them "from the map," like breaking a scout.

Plus.

- Learning - reduce the bonus to experience (numbers need to be adjusted), but on the expert level, don't forget the skill; instead, change it to any basic skill of the player's choice.

30/50/70 - there's no point in making it any lower, in my opinion, and leave the forgetting mechanic as is.

- Ballistics - increases the range of direct fire by 2/4/unlimited (currently 1/2/4), and on the expert level, ignores walls (similar to Guardian Angel).

Plus.

- Give specialists in armor and logistics a 2.5% bonus per level. For now, let's not touch offensive specialists; they don't seem to be overpowered.

Definitely a plus.
- Add Yavor's scripts for the Inferno patch, new constructions, and the symmetrizer to the standard package. Enable the Inferno patch by default (remove the checkbox), and make the rest optional (with a checkbox).

Not sure about this.

- We need to somehow improve the Tavern faction; it's a very weak castle. For now, I don't want to touch the heroes from the Tavern; it's still unclear what the skill balance will be, and even with heroes alone, it won't help much, so we need to change the building tree and prices. Specifically, make mages a dead-end branch; after golems, immediately build giants or nagas, and after nagas, build giants. This way, you can build 1-3, 5-7 in the castle on the first week and get a decent supply of meat to open various things. Also, reduce the cost of building and upgrading giants to 5000/20000. You can also reduce the upgrade cost for nagas.

Make mages a dead-end branch, reduce the cost of building and upgrading giants - plus. And finally, give Fafnir the choice of armor, offense, or tactics instead of literacy. It would also be good to somehow bring back the golem's niche.

- Let go of the complexes about the starting army and give Ufretin, Crag Hack, Edric, and Korbach an army like the regular heroes of the corresponding castles.

Plus. Add Pyradrama and Tiras here, as already mentioned.

- I would also like to cancel the "replace scrolls with gold" option.

Plus, we need to get rid of unnecessary checkboxes.

- Add necromancy.

This is definitely nonsense. Necromancer is already self-sufficient. Perhaps Goshe's starting skeletons could be slightly reduced.
Regarding the Inferno proposal - remove the influence of "+ to HP" artifacts on demon resistance, i.e., increase it only based on the monster's pure HP. With this and the fix for Murray, the castle will be balanced, and there's no need to change anything in the building tree.
