Understood. But Nila, and many others in the Tower, also have Literacy. Nila is good because she immediately gets Air magic. And mass acceleration for upgraded Nagas turns them into dragons:) with retaliation, only without wings:).
In general, Nila is good, unlike Tazar and Mephala, because she starts with a spellbook right away, which is very cool, and Literacy is also a plus. The only downside is that Earth magic rarely comes up for her.
I've played about 100 times with Dungeon, Necropolis, Stronghold, Inferno, Rampart, Fortress, and Tower. Tower has the slowest results.
Here's what causes me difficulties:
1. When a ranged unit blocks the road at the start, it's a problem, because ranged units always take down level 1 monsters first, which Gremlins are, and Gremlins are very fragile.
What can be done about this? Because under certain circumstances, this can significantly slow down development.
2. Titans are a dream for a balanced build in the early game. Therefore, the main troops are Nagas, but even upgraded ones are very slow on the march, not to mention Golems.
In other words, the army is very slow. In battle, mass acceleration solves the problem. But Air 3 still needs to be upgraded. And in the early game?
3. But Golems are excellent as meat shields or for absorbing damage. When taking Ulia, 12 snakes cannot take down ONE Golem in one turn. You enter Ulia with 3 Golems and a few Nagas and easily take it. Utopias are also easily taken with the loss of a few Golems, slightly more than in Ulia:).
Ranged units. It's not always necessary to break through with the main hero. I remember a hero named Kalt, for example. By the way, remember that Defense (skill) also works against ranged attacks. As an option, detach the Gremlins and, if possible, kill them with magic (Gargoyles block, but don't attack). You can sacrifice some irrelevant unit in such a battle.
The first 4 levels of troops on small maps either solve the problem against the AI.
Play more aggressively, buy more heroes, more troops.
