Accumulates experience as you complete Dungeons, Battle Arena and Bomber Royale matches. When fully charged it produces 1 Tentacle of Q’bthulhu. Obtained at the Shadowy Market in Shadow Arenas.
The Tentacle Tract is a Tome bought in the Shadowy Market for 15 Hearts of Darkness. When the Tome fully charges, it will grant the player 1 Tentacle of Q’bthulu. Unlike Legendary Tomes (that can only be used once a week), these tomes can be used as often as you like without any cooldowns, however, they do not provide as many rewards as the Legendary Tomes per individual use.
