Can only be attached during phase 3 to an Underdark realm. This fungus alerts defenders, allowing them to activate their powers first. 'When attacking' and 'Before combat' powers of champions owned by opponents do not work while this ally is in play.

The shrieker has been officially bluelined as "Underdark."
This card is nearly worthless if not in a Underdark themed deck (or at least with a significant Underdark flavor), becoming a just a +1 ally, which is the same thing it is whenever played into battle from hand.
What makes the Shrieker worth playing is that it can be attached to an Underdark realm during phase 3. Once "planted", the Shrieker has two powers. First off, this player becomes immune to powers that activate "When attacking" or "Before Combat". Examples of this kind of power include Agis (261/1st) and The Elf Prince Fhileraene (89/BR).
This even stays in effect for when the Shrieker's owner attacks (but not affecting his cards), and even when the Shrieker's owner isn't involved. Also, when the Shrieker's realm is attacked, defenders can use their powers first, which is very important when using or fighting instant win cards.
As most of the "Before Combat" type powers aren't that common in tournaments and the Shrieker's attachment requirement, the Shrieker won't be seen in many tournament settings, but it is a great support card for fun decks using enough Underdark realms.
