All castles in Heroes 3.

only the units of the Elves are strong, and in general, magic doesn't work well on them.

It's not very clear what you meant by that. Blessing magic from your hero affects the Rampart army no worse than any other (and much better than the Necropolis army), and attack magic hits an elf, centaur, dendroid, or pegasus just as hard as any goblin.
It's a different matter if the hero develops Resistance - then unicorns, pegasuses, and dwarves will add significant difficulty for the enemy mage.

Perhaps your "magic doesn't work well on them" meant something like that? We're just guessing...

show me someone who carries level 1 units with them in the late game!!!! That's ridiculous!!!

I do... I like that the computer so naively and diligently switches to destroying them; it makes it easier for me to resurrect my army - I don't have to waste slots on a bunch of dead units. And, in general, they shoot - and when the hero is level 25+, even gremlins hit very hard (besides, there are already several hundred of them).
What is this habit of arguing your position with the words "ridiculous" and increasing the number of exclamation marks?.. It's almost Neanderthal...:smile19:

It's better to take someone who is really needed at the moment instead of them, for example, if you need a strong :smile25: heavyweight :smile25: to protect the archers (and no one at level 1 can claim this), I usually take either a minotaur, an ogre, or a dendroid. They will protect the archers and help the main forces in battle, and if it's ogres, they can also cast Bloodlust.

Where do you get ogres, minotaurs, etc., on demand if you're playing as the Tower? But even if you found such castles, did anyone raise the population there for you from day one? Covering the archers with the 500 centaurs or halberdiers accumulated at the beginning of the game seems much more promising than 10-12 ogres or minotaurs that you scavenge in a captured enemy castle.

The Titans have their own trump cards against the Rampart, but the Rampart has even more of them, and the Rampart will give any castle a big advantage, perhaps except for Conflux and the Dungeon (these castles are the most inconvenient for those playing as the Rampart).

All this, of course, sounds incredibly convincing, but can you name these "trump cards" of the Tower and tell us more about the "advantage"? It seems like we're discussing tactics here, not stating axioms.
