Look up Warhammer 40,000 Crusade content: Battle Traits, Crusade Relics, Battle Scars, and Boon tables. Covers all three tiers BSData tracks — generic/universal (e.g. Battle Scars), faction-specific (e.g. Chaos Space Marines' Codex Battle Traits), and campaign-specific (Tyrannic War, Pariah Nexus, Nachmund Gauntlet, Armageddon). 11th Edition only — this content isn't tracked in BSData for 10th Edition.
