Terror Models that cause Terror also cause Fear. Fear-causing models, being quite scary themselves, treat Terror-causing monsters as causing Fear, rather than Terror – this is an exception to the rule that makes Fear-causing creatures immune to Fear. Terror-causing models are themselves immune to both Fear and Terror. This includes characters riding Terror-causing mounts, which count as causing Terror themselves.
If a Terror-causing creature declares a charge, the target unit must immediately take a panic test to quell their Terror. If the test is passed, all is well and the unit can declare charge reactions normally. If the test is failed, the unit must make a Flee! charge reaction. Units composed entirely of Fear- or Terror-causing models are immune to Terror and so do not take this test. Note that, if the target unit is not allowed to take any charge reaction (if, for example, the Terror-causing unit charged as a result of a pursuit or a random move), then the target does not take this test.
