Deadly Hail: The many trials endured by the Sempiternals have led their Lord-Ordinator to ensure that every missile is imbued with potent Azyrite magic. You can re-roll woundrolls of 1 for attacks made with missile weapons by units from this battalion if they are wholly within 12" of the LORD-ORDINATOR from the same battalion.
Roll a dice. If the roll equals or beats the attacking weapon’s To Wound characteristic, the attack wounds the target and your opponent must make a save roll. If not, the attack fails and the attack sequence ends. An unmodified wound roll of 1 always fails and an unmodified wound roll of 6 always wounds. A wound roll cannot be modified by more than +1 or -1 (this is an exception to the principle that abilities take precedence over core rules).
