Rook Brutes brings heavyweight fighters into your gang, matching the Blighters' own brutes. It follows Rook Watchers in the archetype line.
Rook Brutes is entry 11 of 17 in the Ringleader branch, one of the three branches (Ringleader, Insider and Swindler) on the Rooks' 39-upgrade board. It is bought with money and materials, not skill points: £5,000, 50 Leather. Before Rook Brutes unlocks you need Rook Watchers.
