As the battles under the Gnarlwood intensify, warbands struggle to establish control over even the smallest areas of the rootmaze. A canny strategist knows that the answer lies in doughty fortifications - so their warriors rig unclaimed territory with traps and build up walls into an unbreachable bastion, even as the enemy approaches. The most successful combat engineers may even claim the title of Castellan of the Fearsome Fortress!

Get stuck into Warhammer Underworlds or mix up your game with the complete Fearsome Fortress Rivals deck, usable by any warband - including those from past seasons. These cards can be used as a standalone deck in Rivals games, mixed with a warband's unique cards for Nemesis games, or used to build a deck from the ground-up in Relic games. This deck doesn’t include any spells, so warbands from any season can put it to good use. Each card is brand new to the game, focused on using feature tokens to create defensible positions. Board control warbands such as the Sons of Velmorn, Skittershank’s Clawpack, Hexbane's Hunters, and Grinkrak’s Looncourt will find Fearsome Fortress particularly suited to their play style.

This deck contains a 32-card universal Rivals deck, consisting of:
- 12x objective cards
- 10x gambit cards
- 10x upgrade cards
- 1x plot card with additional rules for using the Fearsome Fortress deck

You'll need a Warhammer Underworlds warband, including their fighter cards, to use the contents of this deck.

The Rivals format is designed to be the most accessible way to play Warhammer Underworlds, as players face off using pre-made decks in a test of skill.

Rules for all formats can be found on the Warhammer Community website.
