Choice | Mission 1: The Other Elves - side quests Heroes VI - Shades of Darkness Guide

Objective: Reach the Blood or Tear class

Reward: +2 Destiny

Just choose any path and keep following it. Unfortunately the first mission doesn't have too many neutral enemies and just a few side missions, so you will need to completely clear the map to finish this quest. You should keep using the chosen skills category from the very start and the mission should end just before the final battle.
