If possible, Eikaba will position himself so that he threatens both enemies; if not, simply the closest one. He will attempt to stay in between the enemies and Lucien. He will then ready an action to attack the first demon to take a hostile action.
Attack: [roll0]
Damage: [roll1] (If it matters for the purposes of DR, all of Eikaba's attacks count as magic, good-aligned and adamantine.)
Active Stance: Iron Guard's Glare
If either enemy provokes an AoO from Eikaba by moving, he will use
Stand Still in place of a normal attack; I'll let you roll that yourself to save time if it becomes relevant.
