Sanctuary - "Ashes and Fury" [Campaign 4 - Mission 1]

Could you please advise which skills are best to develop for Irina and which spells to use in everyday battles?

Reinforcement 1 (for the first battles without losses)
Air 1
Meditation 1
2 passive skills that improve magic attack (they are in the general skills, I don't remember the name)
Lightning 1
Air 2
and improve Meditation and the two skills:smile01:
the number of levels should be enough
it is desirable to get the Blood skill, it is more useful
but if you like the skills with tears, then learn to use them.
