Here's an idea: Aeliana's biography states that she is an 'elf of two bloodlines.' Perhaps we could give her the foundations of irresistible magic? Just for fun. It shouldn't help too much at the beginning, as there are no black dragons, and chaos won't save the day in the end. But a hero with two racial skills would be very interesting.

It's quite possible. For example, among the Necromancers, there's a specialist in both necromancy and irresistible magic. A character like that, a dark-skinned one, and also with necromancy:)
I can add it if there are no objections. The only thing is, how will the enhanced spells work with the enchanted ballista?...
And with the blue druids, an enhanced spell accompanied by a ballista will probably be terrifying...

It's already been added... I've slightly reduced the number of blue druids at the start. I've uploaded version 1.1.
