Seneschal of the Keys

A Warlord with this Trait may select any one Faction (for example, Mechanicum, Dark Mechanicum, Daemons of the Ruinstorm, Legiones Astartes (X), etc). Once per battle, the Warlord’s controlling player may, at the start of any of their own turns, declare that turn to be Decisive. During the Decisive turn, the Warlord and all models in a unit he has joined may increase their WS or BS by +1 when making attacks against a unit that includes at least one model from the chosen Faction. In addition, an army whose Warlord has this Trait may make an additional Reaction during the opposing player’s Assault phase as long as the Warlord has not been removed as a casualty.
