when is that even the case?? mines (unlike Shakti) are needed by everyone-))
ore, for example, or some little tree......
crystals and gems are also needed - an unupgraded vampire is a dead vampire-))

What is meant is that it's not fatal for a Necromancer to go without some mine entirely, or to take it on the second week, or to collect them in clusters. A good Necromancer player can crush others from 1 to 3 weeks without adding armies from the Castle, and doesn't worry much about the imminent rebuilding of the castle ... which cannot be said for others

Shakti turns out to be a pretty good warrior. I sometimes take him as the main one. Starting skills are good, he pumps defense and attack up to level 10 with a 35% chance, after ten - 30%. What's wrong with that?

As a warrior he is good, but the specialty ... the further you go, the more useless it becomes ...
