Grail

Source: Codex: Blood Angels, p. 17

A Sanguinary High Priest, standard bearer or Blood Angels Chaplain may carry a chalice or Grail into battle with him. These items are used during the Blood Angels' holy ceremonies and are an inspiring symbol to the battle-brethren of the Chapter. Any Blood Angels unit with a model within 6" of a character with the Grail may roll an extra dice when making an advance after winning a close combat, and discard the lowest roll before working out how far they move. For example, if a Blood Angels unit rolls a 3, 4 and a 6, the 3 is ignored and they advance 10". This combines with any other ability the unit may have so that, for example, a unit with jump packs may roll 4D6 and choose the three highest scores.
