Erling in Heroes 5

All Rune Priests, Rune Patriarchs and Rune Keepers in hero's army gain +1 to their Attack and Defense for every two levels of the hero, starting on first level.

The tame white owl, Trolinga, who slumbers peacefully on Erling's shoulder, was with him when Erling returned from an extended winter trapping expedition. Questions about it meet only with a secretive smile. As well as the owl, Erling returned from that journey with a profound knowledge of Dwarven Rune Magic, and many Dwarves wonder just exactly where he went that winter, and who he met.
