Vial of the Fulminator

The highly combustible oil within this vial is the perfect fuel for explosively accelerating Skryre war machines across the battlefield.
At the start of the movement phase, pick a friendly Skryre War Machine unit within 3" of the bearer. You can double that unit's move characteristic until the end of the phase. However, if you do, that unit suffers 1 mortal wound at the end of that phase.
