Unlocked in Wayrest – Episode 5 – Silverhome on the Water, Back Room.
Garnag, Dark Adherent can be a challenging card to use properly. It hamstrings late-game decks that depend on large amounts of magicka, and can also be used to counter Magicka Jump decks. However, Garnag's magicka restriction can also limit the player's ability to respond to their opponent. Garnag does not work well in decks that specialize in high-cost cards, but can be very effective for aggro and mid-range decks at limiting the opponent's ability to respond.
