Logan Grimnar on Stormrider [Legends]

Before the battle, in the Muster Armies step, for each leader and support unit in your army, you can select one friendly bodyguard unit that unit can lead. That unit will then lead that bodyguard unit for the battle and form an attached unit with it. Unless otherwise stated, each bodyguard unit can only have one leader unit and one support unit attached to it.

This ability always takes the form **Deadly Demise X**. Each time a model in this unit is **destroyed**, after the units embarked within it (if any) have made their **emergency disembark moves**, roll one D6. On a 6, that model suffers a **deadly demise**; each unit within 6" of that model suffers a number of **mortal wounds** denoted by **X** (if this is a random number, roll separately for each unit within 6"). 
***Example:** An Impulsor with a unit of Intercessors embarked within it is **destroyed** by ranged attacks. First, any unresolved attacks made by the attacking unit are resolved. Then the Intercessors make an **emergency disembark move**. Then the roll is made for the **Deadly Demise** ability, and on a 6, that ability is resolved. Finally, the Impulsor is removed from the battlefield.*

If your Army Faction is **^^Adeptus Astartes^^**, at the start of your Command phase, select one unit from your opponent’s army. Until the start of your next Command phase, that enemy unit is your Oath of Moment target. Each time a model with this ability makes an attack that targets your Oath of Moment target:
■ You can reroll the Hit roll
■ If you are using a Codex: Space Marines Detachment and your army does not include one or more units with the **^^Blood Angels^^**, **^^Dark Angels^^**, **^^Deathwatch^^** or **^^Space Wolves^^** keywords, add 1 to the Wound roll as well.
