Mages – their development.

So, with the Overlords, there are now 3 options, right?

Well, un-upgraded ones don't count...

city building

If it's a generator, the tavern is already built... accordingly:
Day 1 - Goblins
Day 2 - Mage Guild level 1
Day 3 - Forge/Gargoyles
Day 4 - Gargoyles/Forge
Day 5 - Town Hall
Day 6 - Golems
Day 7 - Mages
-------------------------------------
I want to clarify right away... I always capture 4 main mines in the first 2-3 days (2 wood and 2 stone). This is necessary for successful construction and to have some resources left for future trading... Because resources are often scarce.
I've outlined the first 7 days; the rest depends on the situation, the amount of resources on the map, etc...

hero leveling

Leveling up the hero is more difficult; you need to know the opponent's strengths... The main skills:
1. Sorcery
2. Education
The rest depends on the opponent. (This is for leveling up a regular mage, not a combat mage - Razazak)

creature development

Upgrades are also chosen depending on the opponent.
