Hello Patriksun,

We have explanation for the changes but in English for artifacts here and for difficulty system here.

I will try to explain both of them also here.

Artifacts

what is important to know is the picture below.
It explains what boosters can be found for each slot. For example:
- in Main Hand slot you can get artifacts that boost Attack for values between 1 and 8 included and also artifact that gives 12. the same is for spellpower.
- in Finger slots you can find rings that boost 2 of a primary stat (attack, defense, spellpower, knowledge) and you can also find rings that boost both Attack and Defense by 1 or Spellpower + Knowledge by 1.

The only peculiarities are the slots that have "-" sign. this means you can get Artifacts that reduce enemy stats (morale and luck).

Besides that you can download the external manual. Go to artifacts section and filter by slot to see what can be found.




GAME DIFFICULTY

Check the new descriptions in RC15 Beta 3. They were simplified and made more accurate. Does that solve the issue?

A lot of new 'tech' is implemented, making it necessary to do another beta before the campaign integration. Combat Scripts now work in multiplayer and H55 now includes almost the complete LUA 4.0 Library and all those functions work on the adventure map and the combat map. These technical enhancements allow a lot of new features and creativity for mapmakers. 

This release is the largest code revision since RC1 and is not compatible with all mods and submods (without updating) except duelist pack. Unique hero models also need updating. Please note the huge expansion of our compatible maps database here. More maps may still follow, but they just require more work. Also a total campaign remake with all RC15b3 features is coming soon (~Q2 2022). This release contains many new innovative features that need feedback, to make sure the game is 100% to player satisfaction before the campaign is added.

A large amount of bugs was fixed in the scenario maps (maybe all of them) and performance of many scripts is improved. The game now always knows the type of map you are playing therefore the AI/Gamemode tooltips from previous release have been simplified and cleaned up of most warnings (you can't really do anything wrong except making the game much too hard for yourself), the old random setting now functions purely as a help text and shows a question mark icon.

Mine Control
You can now revisit every mine you own and a question box will appear asking you if you want to guard it for a small sum of money
