Oath of Duty
This Oath may be selected by a Kill-Team which has selected a Battle-Brother of the Ultramarines Chapter to be their leader. Oath-taking is described on page 228 of the Deathwatch Rulebook.
Taken upon a volume of the Codex Astartes, the Oath of Duty is an avowal of one’s duty, stated for all to hear and its fulfilment is promised upon a sacred tome. The Ultramarines hold that an oath sworn upon something sacred is unbreakable, for to break such a vow would not only be disgraceful, but blasphemous, and few can refute such reasoning.
Prerequisite: Any Battle-Brother of the Ultramarines Chapter.
Effect: Those that take the Oath of Duty meditate upon the task at hand, focussing utterly on the completion of their immediate task, with no consideration of anything irrelevant to their mission. Such focus grants the members of the Kill-Team the freedom to approach the mission’s objectives in any way they choose, unfettered by any other considerations.This Oath grants no special ability, but rather grants access to four Squad Mode abilities instead of three.
