Tips and tricks for playing Heroes 3.

I'd like to hear about original strategies you've used during gameplay, both on the map and in battles. Ideally, provide examples of "tricks" specifically for Heroes 3, not 3.5. Share any clever tactics, from simple ones like "using one Harpy to destroy a Golem Legion with Wait, taking advantage of uneven terrain," to more complex strategies, such as "controlling your home castle even when you're a week's journey away." For example: your main hero and their entire army set off into the unknown in search of artifacts. Suddenly, an enemy hero appears... right near your castle! To avoid being caught off guard, set up a chain of 6-7 heroes, each one day's travel apart, leading from the castle to your main hero. When danger is detected, the main hero transfers ALL troops to the nearest hero in the chain in just ONE day. That hero then passes them on, and so on, until the troops reach the castle. Meanwhile, the main hero disappears near a neutral creature, pays a small fee to teleport to a castle where the entire army is already waiting. It's a kind of clever teleport. If there's still a turn left, you can even manage to attack the "guest" on the same day. I'd like to hear about similar situations
