User blog comment:Lasifer/Hellstorm Issue 6: Beowulf vs. Achilles/@comment-4661256-20130619215941/@comment-8012490-20130624220650

So, wait, is the spear enchanted so that only Achilles can lift it or is he just the only one strong enough to lift it? If he was the only one strong enough to lift it, than people stronger than him (Hercules or Beowulf) could also lift it and Naegling would get the edge because if Beowulf could lift it than he could presumably break it as well.
