Living Fog - Age of Wonders 4 Astral Shadow Build Guide 

Out of date, Living Fog is now a mythic unit and doesn't benefit from unit enhancements, still a good unit though.

Ive used a very similar build with a little more focus on city building. Extra note is that the final astral empire upgrade + mana channelers makes them come out extra strong and elementals auto evolved (for cheap summons)

How do yo get those units? Just from rally the leiges ??
