immortal
Auto-translated
1) Astral Gate rule for all templates.
2) Yes, the mentor is not in the skills on the Tournament Edition, so the point is unnecessary; we'll remove it (point 11 was carried over from the previous tournament; we'll fix it).
3) On maps with IRMG (Increased Resource Multiplier Growth), it is possible to use a mentor and a Fortress because on the Tournament Edition, you can forget a maximum of 5 skills in a row with a mentor, and then each forgotten skill will take up the entire hero's turn, meaning you can only forget one skill per turn. The Fortress, however, spawns in not very popular zones, and it also has serious guards, plus it would be boring without it.
