Do you know how to play?

I don't really know what actions need to be taken here, especially when playing as Solmyr. That's why I would really like to learn from the experts. I remember a friend playing as Solmyr, casting two lightning spells on the neutrals and then running to the Castle to replenish his mana, staying there for a day, casting a couple more lightning spells, and gradually eliminating all the neutrals around him.

Probably not all of them, but definitely monsters of levels 1-5... It's easy to start with Solmyr. :) Kira and Solmyr are the two strongest heroes for the Tower. Kira has an advantage due to her initial diplomacy, which is a bit of a cheat. And Solmyr has a chain of spells... When Hero III first came out, I really loved playing as the Tower... it was beautiful! :) The music is so relaxing. I love Hero III.
