Grav-gun

The weapon uses a Blast marker.

Any model hit by a Concussion weapon has their Initiative reduced by 2 to a minimum of 6+ until the end of the round.

Instead of rolling to wound normally with this weapon, any model caught in the blast must instead roll equal to or under their Strength on a D6 (a roll of 6 always counts as a fail). After the weapon has been fired, leave the Blast marker in place. For the remainder of the round, any model moving through this area will use 2" of their movement for every 1" they move.
