Cytheron Pattern Aegis

The Cytheron pattern aegis can be used in one of two ways: it can either provide the bearer with a 4+ Invulnerable Save against Shooting Attacks and a 5+ Invulnerable Save against Melee Attacks, or it can be deployed. The controlling player may choose to deploy the Cytheron pattern aegis at the end of any of their own movement phases (the unit must be deployed on the battlefield and not Embarked upon any model) as long as at least two models in the unit are equipped with Cytheron pattern aegis - all models in the unit that have a Cytheron pattern aegis must deploy them to get this benefit. While deployed, the entire unit gains a 4+ Invulnerable Save against Shooting Attacks and a 5+ Invulnerable Save against Melee Attacks, and any enemy models Engaged with a model from this unit in an assault have their Initiative reduced by -1. The controlling player may choose to end the deployment at the start of any of their own Movement phases, or if the number of Cytheron pattern aegis-equipped models in the unit drops below two, the effect immediately ends.
