Go to 1:05 (Where the Riekling camp is shown). Listen and look very carefully and closely. Hear that? See that?

When the Mounted Riekling lunges at him with the spear, you hear an arrow shot noise and an arrow seemingly come out of the spear. This may or may not confirm that Spears act like arrows, but its for you to judge.

Wanna know a rumor? Well a rumor is that the spears are unusable by our character and once picked up.. They become arrows.. And the chances of this is high.. I believe.. Or the rumor has gotten a lot of ground and is false..

Old as [censored]ing dirt.

Yep. Go Back to the day when the trailer was released.

Yes based on a ''rumor'' (which may have or not have been a leak) I've also heard they are used as arrows.
