Vortex Grenade

Anything covered is automatically destroyed, anything partial is destroyed on a 4+. This includes vehicles, terrain, etc. If a vehicle is partially covered, each location on the vehicle covered by the vortex is hit on a D6 roll of 4+ — the vehicle‘s armour is penetrated automatically; roll for damage on the appropriate table with a +1 modifier.No armour save is possible at all. Vortex blocks out sight and cannot be fired through. At the beginning of each subsequent player turn roll a D6 and consult the below chart:

1-2: Vortex disappears
3-4: Vortex remains in play
5-6: Vortex moves D6" in a random direction determined with a scatter dice
