Where His Skills Point

Rear Escort, Crescent Tactics, Defensive Order - Footmen, and Awaken all name Footman squads directly, not Siege units. Only his active skill and Dual Strike carry the immunity and damage-reduction effect onto his own squad, the one actually sitting in the Siege slot. Rear Escort in particular buffs Footman and Cavalry squads together with a Raid-style extra attack chance, a bonus that never touches the Siege squad Hannibal is parked in.

The Slot Left Out

Put Hannibal in his Siege slot with no Footman squad anywhere in the same formation and Rear Escort, Crescent Tactics, and Awaken all sit there with nothing to buff. His own squad still gets his personal defensive effect regardless, since that part is tied to Hannibal himself, not his slot type. The four Footman-tagged skills are the ones that go quiet.

Reading Before You Build 🧩

The fix is not moving Hannibal out of Siege, since his personal survivability skill needs him there. The fix is making sure a Footman squad exists somewhere else in the same formation so his four Footman skills have a target.

Have you checked whether your current formation actually has a Footman squad standing next to Hannibal's Siege slot? 🛡️
