Embora tenha sido deixado vago em alguns lugares, fica claro que, após o Breaking of the Fellowship, ele pegou flechas de Orc (fonte: The Two Towers, a Partida de Boromir ):
'And I,' said Legolas, 'will take all the arrows that I can find, for my quiver is empty.' He searched in the pile and on the ground about and found not a few that were undamaged and longer in the shaft than such arrows as the Orcs were accustomed to use. He looked at them closely.
Apenas Orcs participaram do ataque à Irmandade, então, portanto, só podem ter sido flechas de Orc.
