Final Thunderstrike

You can use the command ability once per battle at the start of the combat phase. The command can only be issued by a friendly KNIGHT unit to a unit wholly within 12" of them or by a friendly LORD or DRACONITH to a unit wholly within 18" of them. The unit that receives the command must be a friendly STORMCAST ETERNALS unit. Until the end of that phase, add 1 to rolls for the Blaze of Glory battle trait when a model in that unit is slain.
