Lost through war and catastrophe over the centuries, only a handful of Blood Chalices now remain; they are only entrusted to the most faithful and deserving members of the Chapter. However, fragments of destroyed Chalices are worked into the Nartheciums of the Blood Angels' Sanguinary Priests.[1b]
A Battle-Brother may drink from the Blood Chalice, removing any fatigue, damage or wounds (though not restoring lost limbs or other permanent injuries). Only Sanguinary Priests are ever entrusted with a Blood Chalice.
