If the Harbinger of Bast dies, the lions do not take take a Rout Save at a -2. They are overcome with their blood rage and attack the killer of the Harbinger.

The lions (like other beasts) can adopt the following formations: Mob, Line and Column. If the player chooses, the Harbinger of Bast may attach to the lions and lead them directly.

Vitriolic Mocking:

This Gift can be used by a Harbinger of Basti against a target with which it is currently in Provocation. If the enemy Harbinger is in melee combat with other models/units, then Line-of-Sight is blocked as normal and Vitriolic Mocking cannot be used.
