Very useful in that it's an unconditional Skill Boost to any Red Card.
Requires Aphoom-Zhah to be Subbed on the same Main Card to reach maximum effectiveness though.
Something worth noting is that if you have two Fthagguas, their Sub Skills do stack together with Aphoom-Zhah, allowing you to get a get a 25% Skill Boost from all three cards.
Fthaggua is the regent of the fire vampires, and like his minions, gains energy and knowledge from the intelligent creatures they slay.
They serve the Great Old One Cthugha.
