1. You can't block passages with new reinforcements that your opponent could use to bring up their reinforcements.
But what if you've run out of moves?
2. New heroes are not considered reinforcements unless they bring 1 unit with them.
If a hero is needed, can you play with them, and then either dismiss their reinforcements, leaving only one unit, or
leave the reinforcements in the castle and go with the hero and one unit?
3. Forbidden heroes must be dismissed IMMEDIATELY upon reaching level 5, along with the army they reached level 5 with? Or can you transfer the army and then dismiss them?
4. Forbidden heroes of level 5 and higher, released from prisons, must be dismissed immediately? Can you take the army that came with them?
* you cannot use heroes without an army
what does this mean?
In this case, on the next day, they will have maximum growth.
Some versions have ways to create such heroes.
And if you don't know how, it will be very difficult for you to violate this rule.
in Necropolis and Stronghold, the starting hero is random. You cannot build a Necromancy Amplifier, upgrade Vampires, Faeries, Phoenixes, and Air Elementals. If the computer builds any of these, you cannot upgrade your own creatures or buy upgraded creatures. You do not need to disband additional skeletons.
i.e. can you raise skeletons?

The other day, one (who is far from a novice) sincerely believed that the Amulet of Sacrifice was just lying next to a pack of Necrodrakes guarding a mill)
