The Ordo Malleus stands in open feud with any daemon or warp-touched force — a Chaos Daemons warband, a warp-cult, or a Khorne-marked gang whose Blood Tithe it was raised to break. This is never a truce and never a bargain; the daemon is prey, not a partner, and the Malleus can make no peace with it. While the feud holds, the warband gains +1 reputation for any battle in which it takes a daemon or psyker enemy Champion Out of Action, and once per campaign phase it may declare a Containment battle against the feuded gang. The daemon force is granted nothing in return — the feud runs one way, toward the veil.

Whoany daemon or warp-touched force — a Chaos Daemons warband, a warp-cult, or a Khorne-marked gang (the Blood Tithe cult the Ordo is purpose-built to break) — never a truce, always a hunt
Termsa standing campaign feud, not an alliance: the Malleus can never make peace with a daemon force. While the feud holds the Malleus gains +1 reputation for any battle in which it takes a daemon or psyker enemy Champion Out of Action, and may declare a Containment battle against the feuded gang once per campaign phase; the daemon force gains no terms in return — it is prey, not a partner
Whoanother Ordo of the Inquisition (an Ordo Hereticus or Ordo Xenos warband, any pairing — never a fixed named House) that shares a hunt against a common heresy, lending tools rather than bodies
Termsa campaign-level, phase-gated shared-hunt pact: while it holds, each Ordo may lend the other ONE support-roster tool (a single fighter or a single relic) for a joint battle at cost, and both observe map-level non-aggression. No cross-Ordo fighters join a normal-battle gang list. The pact opens only at a world's incursion/purge phase and dissolves when the shared enemy is broken
When a shared heresy demands more tools than one Ordo can carry, the Malleus will strike a pact with another Ordo of the Inquisition — a Hereticus or Xenos warband, any pairing, never a fixed name. It is a lending of tools, not of bodies. While the pact holds, each Ordo may loan the other a single support-roster tool — one fighter or one relic — for a joint battle at cost, and both observe map-level non-aggression. No cross-Ordo fighter joins a normal gang list. The pact opens only when a world enters its incursion or purge phase, and it dissolves the moment the shared enemy is broken.
