Doombull

You can use this command ability at the start of the combat phase. This unit must issue the command and the unit that receives the command must be a friendly WARHERD unit within 12" of an enemy unit and more than 3" from all enemy units. If you do so, you must attempt a charge with that unit.

If the unmodified hit roll for an attack is made with a melee weapon by this unit is 6, that attack causes a number of mortal wounds to the target equal to the the weapon's Damage characteristic and the attack sequence ends (do not make a wound roll or save roll).

After this unit makes a charge move, you can pick 1 enemy unit within 1" of this unit and roll a dice. On a 2+, that unit suffers D3 mortal wounds at the end of that phase.
