Karli in Heroes 5

All Spearwielders, Skirmishers and Harpooners in hero's army gain +1 to their Attack and Defense for every two levels of the hero, starting on first level.

Karli spent many a year in the underworld smithies, studying ancient formulae and experimenting with various alloys and components in order to create the finest weapons possible. The warriors led by Karli have the best-balanced arms, giving them noticeable advantages in the battlefield.
