The Return of Yashtar | Mission 1: A Selfish Prayer for Light - side quests Heroes VI - Shades of Darkness Guide

Objective: reach level 7 and return to Yashtar's Laboratory

Prize: 2000 XP, 60 Spectres, 30 Lamasu

You will complete the first part of this mission automatically during other missions. Yashtar's Laboratory (M1, 12) is best visited during your march on the angel leader (M1, 13) as part of "Aggressive Light - part 2". The Lamasu you obtain that way will make the upcoming battle easier, while also letting you place a building in Nelsham-Nadin which will let you recruit more creatures.
