Shrieker Echo is a unique attack skill exclusive to Druids.
When enemy units are within range, Shrieker Echo activates, summoning myconids that let out a shrill cry, stunning enemies near it.
Because the cry can be heard from long distances, this skill can be used as a convenient early warning system. However, it is far from perfect as enemy units may be able to skirt around the skill's range.
