Cthulhu Wars: Great Old One Pack Four is an expansion for Cthulhu Wars released in 2016 for 2–4 players, 90–120 minutes per game, and ages 12 and up. It was designed by Sandy Petersen and its main mechanics are Variable Player Powers, Area Movement, and Dice Rolling.
Cthulhu Wars: Great Old One Pack Four adds three new Great Old Ones to Cthulhu Wars. As in the other Great Old One Packs, each Old One may be added to any game of Cthulhu Wars and is available to all factions on a first come, first served basis. Each Great Old One has its own special ability, plus its own unique spellbook, which is earned separately from your own. The Old Ones in this pack are Byatis, Nyogtha, and Tulzscha. Byatis lures enemy cultists to their doom, Tulszcha subverts the purpose of the Ritual track, and Nyogtha takes prisoners away to its lair.

Setup and teaching time are not included in this estimate.
