Lord Discordant on Helstalker

If this model destroys one or more enemy VEHICLE models with a melee attack, then until the end of the battle, it can use the Corrupt Machine Spirits ability twice in your Command phase.

In your Command phase, this model can corrupt either one enemy VEHICLE model within 9", or one friendly VEHICLE model within 9":

• If it corrupts an enemy model, roll a number of D6 equal to the Wounds characteristic of that model: for each 6, that model's unit suffers 1 mortal wound (to a maximum of 6 mortal wounds).
• If it corrupts a friendly model, until the start of your next Command phase, each time that model makes a melee attack, add 1 to that attack's hit roll. Each model can only be corrupted once per turn.
