Rotigus

At the start of the Fight phase, you can select one enemy unit within 24" of and visible to this model. Until the end of the phase, each time an attack made by a Plague Legions model is allocated to a model in that unit, add 1 to the Damage characteristic of that attack.

While an enemy unit is within 6" of this model, subtract 2 from the Move characteristic and subtract 1 from the Objective Control characteristic of models in that unit.

While this model has 1-7 wounds remaining, each time this model makes an attack, subtract 1 from the Hit roll.

This ability always takes the form Deadly Demise X. Each time a model in this unit is destroyed, after the units embarked within it (if any) have made their emergency disembark moves, roll one D6. On a 6, that model suffers a deadly demise; each unit within 6" of that model suffers a number of mortal wounds denoted by X (if this is a random number, roll separately for each unit within 6").  Example:* An Impulsor with a unit of Intercessors embarked within it is destroyed by ranged attacks. First, any unresolved attacks made by the attacking unit are resolved. Then the Intercessors make an emergency disembark move. Then the roll is made for the Deadly Demise* ability, and on a 6, that ability is resolved. Finally, the Impulsor is removed from the battlefield.

Each time this unit makes an ingress move (20.04), if every model in this unit has this ability, it can be set up anywhere on the battlefield that is more than 8" horizontally from all enemy units, even if that is within your opponent’s deployment zone.

This ability always takes the form Feel No Pain X+. Each time a model with this ability would lose a wound, roll one D6: on an X+, that wound is not lost. 

Each time an attack made with a [DEVASTATING WOUNDS] weapon results in a critical wound, the attack sequence for that attack ends and the target unit suffers a number of mortal wounds equal to the D characteristic of that weapon. These are inflicted after resolving any normal damage inflicted by those attacks.  Mortal wounds inflicted by [DEVASTATING WOUNDS] weapons can damage a maximum of one model for each critical wound; any remaining mortal wounds inflicted by that attack are lost.  Example: An attack made with a [DEVASTATING WOUNDS] weapon with a D characteristic of 3 results in a critical wound against an Intercessor Squad, so inflicts 3 mortal wounds. The first 2 mortal wounds are sufficient to destroy 1 Intercessor model, so the remaining mortal wound* is lost.

Each time an attack is made with a [TORRENT] weapon, that attack automatically hits the target.

Each time an attack is made with an [IGNORES COVER] weapon, the target cannot have the benefit of cover against that attack (13.08), including from rules that give a model or unit the benefit of cover (e.g. Stealth).

Each time an attack made with a [LETHAL HITS] weapon results in a critical hit, you can choose for that attack to automatically wound the target.  Designer’s Note:* Choosing to automatically wound the target means that no wound roll is made for that attack. You may decide against this, as it means that attack cannot result in a critical wound* and so cannot trigger other abilities such as [DEVASTATING WOUNDS].

Each time an attack is made with a [PSYCHIC] weapon, you can ignore any or all modifiers to that attack’s BS or WS characteristic and any or all modifiers to the hit roll. Attacks made with [PSYCHIC] weapons are known as psychic attacks (this can be important for the triggering of other rules).
