NTBF – New buildings for the towns in Tribes of the East 3.1. Auto-translated

For example, for the Sylvan faction:
Tavern gives a +1 bonus to Defense.
Gleaming Fountain gives a +2 bonus to the luck of the defender.
Daughter of Silanna gives a +2 luck bonus to all heroes (including defenders).

Were there buildings that gave a bonus ONLY to the capital?

What does it mean, only the capital? Will it be like Moscow, taking people and food from the provinces?

Hmm, there's another fantastic idea:
A mercenary guild – allows you to hire an additional random unit once a week, similar to the refugee camp. You could also add improved versions that, for example, start selling improved creatures when upgraded, or make it so that the first level of the guild only offers low-level creatures, and the second...

Well, in Heroes, the capital is where the capitol building stands. But here, you also need to understand that its enemy can dismantle it, which makes such buildings seem a bit far-fetched.

Another idea for a building:
Transforms units placed inside for a fee/once a week into other random units of the same level.

Improvement for the shipyard. For a smaller fee, moves the nearest ship to the city to where a newly built ship in the city would stand.

If you're going to upgrade the tavern, it should have more interesting features.

For example, a level 2 tavern could give hired heroes a bonus depending on their race (experience, artifact, stat, movement range, etc.). A multi-level bonus system is possible.

Idea: Hospital

Ability: Protects its troops from dark magic, levels 1-3, for one week.
