My Theories:

1)Power Upgrade--Maybe it'll give their powers a boost!

2)Confidence--Maybe it'll make them feel like they can do/defeat anything(like Felix Felicis)!

3)Fear--It may have a fear effect on the Giants, like Hades's Helm!

4)Intellect Booster--It might make them more intelligent!(I think this is the best one. Not the most likely--but the best one)
