Daemon Flask

Once per battle, at the start of your hero phase, the bearer can use this artefact. If they do so, roll a dice for each enemy unit within 12" of the bearer. You can re-roll the dice for a unit that is a WAR MACHINE or is within 3" of a terrain feature. On a 4+ that unit suffers 1 mortal wound. On a 6, that unit suffers D3 mortal wounds instead of 1.
