Do you have a couple of questions about mentoring?

Moderators, please delete two threads and leave one. Due to a forum bug, the thread was created multiple times! Hello, heroes! I finally decided to write and ask about Mentors and maybe ask a couple of other questions (I don't want to create many threads). After all this time, I think that either I have a "cursed" version of the game, or I'm just "lucky." You'll understand why when I ask the questions. 1) Mentor - where can I find him in the Campaigns? Is he in the original Campaigns and the first expansion, added through a mod in "Lords of the Realm"? 2) What is the principle of Mentor generation in Random Map Generator (RMG)? To be honest, after all these years of playing Heroes, I've almost never seen a Mentor. I have a feeling that either the patch has bugged my game, or I'm just unlucky and everything is generated except for Mentors. 3) In this regard, maybe it's worth installing some additional mod for improved map generation? Maybe then Mentors will finally start appearing? (I wouldn't ask, but when you haven't encountered a Mentor for YEARS...) From this, additional questions arise regarding generation templates and other things: 4) Can someone explain the templates? As I understand it, it is even possible to create them, but how exactly do you specify the generation in them, and even more so, how do you specify the desired details (such as "one exit from the location + 1 portal with very strong guards to another part of the map on your native location")? 5) Is RMG Advanced a worthwhile mod? It seems to add a couple of minor features that, however, improve generation. (Maybe it fixes Mentors?) 6) As I understand it, regarding templates, there is some kind of table of object prices on the map or something similar that allows you to make the generation more accurate in the area by selecting a numerical value. Is there anywhere I can read about this? 7) Is there a mod for balancing campaign heroes in regular battles?
