Tower tactics.

That's Solmyr, and there's another one with a ballista, I don't remember his name, but I always buy him.
I've never used Nilah's magic at the start, out of habit, because Gurnisson always goes without a spellbook for the first week:).

Also, who else from the Tower has magic?

The one with the ballista is called Torosar. I like this hero, although he doesn't have the skill needed at the beginning:)), he has a specialization, but not the skill...

From the Tower, there's a great guy named Tan. The advantage of him is that, in addition to archery, he has literacy, which allows you to establish spell exchange with other heroes!!
For the same purposes, Iona is also good. She brings both gold and has archery.
There are also several heroes with acceleration, led by the legendary Kyra (not Knightly)/Saira. With the help of Tan/Iona, you can teach this acceleration to all the guys.
