Irina in Heroes 5

All Griffins, Imperial Griffins and Battle Griffins in hero's army gain +1 to their Attack and Defense for every two levels of the hero, starting on first level. Griffins get Battle Dive Ability.

Irina's earliest memories are of griffins, as she was born into a respected family of griffherders. She grew up knowing the ins and outs of those proud and dangerous beasts, and when called to war for the Empire she readily brought her gifts to bear where she could do the most good. Irina ensures that the griffins that fight by her side are exceptionally healthy and respond well to commands.
