Alliances2

The Noble Kindred alliance
Whothe noble kindred of the Imperium (a loyal allied Chapter, an order of the Adepta Sororitas, or any zealous Imperial force that keeps the same wars as the Sons of Sanguinius)
Termscampaign-level alliance: while it stands, the Blood Angels and their kindred observe a map-level non-aggression and may lend one favour to each other per post-battle sequence; both gain a small reputation bonus for a campaign won together, and the kindred may steady a Blood Angels fighter against the Black Rage once per campaign

The Blood Angels stand with the noble kindred of the Imperium — a loyal allied Chapter, an order of the Adepta Sororitas, or any zealous Imperial force that keeps the same wars as the Sons of Sanguinius. These are brothers-in-faith who respect the blade even as they fear the Flaw it carries.

While the alliance stands, the two gangs observe a map-level non-aggression and may lend one favour to each other in each post-battle sequence. Both sides gain a small reputation bonus for any campaign won together, and once per campaign the kindred may lend their steadiness to a Blood Angels fighter, letting it re-roll a single failed Black Rage check. The bond is one of shared duty, held for as long as both keep faith with it.

The Patient Hunters alliance
Whoan attrition faction that outlasts the charge (any patient, resilient gang built to grind a force pulled ever-forward and unable to hold back - the Blood Angels' natural predator)
Termscampaign-level feud: while it stands, the Blood Angels gain bonus reputation for a decisive win over the hunters but the hunters gain reputation for every battle they drag past round four; the feud runs until one side is driven off the contested world

The Blood Angels' natural predator is the attrition faction that outlasts the charge — any patient, resilient gang built to grind down a force pulled ever-forward and unable to hold back. The Sons of Sanguinius decide a fight in the first assault. The hunters mean to survive that, and bleed them dry in the long hours after.

While the feud stands, the Blood Angels gain bonus reputation for any decisive win over the hunters, taken before the battle can drag on. The hunters, in turn, gain reputation for every battle they drag past round four — the slow grind the Thirst can never abide. It runs until one side is driven off the contested world entirely.
