Dropped by Gilgamesh during Act 2, the Excalipoor appears to be the Excalibur, listing itself as having 100 Attack Power and being able to be wielded as a normal sword (As opposed to the Knight-only swords, which the real Excalibur is part of).  This is because the weapon's ACTUAL attack power is, in truth, only 1.
However, two classes are capable of using the Excalipoor.  First, the Ninja can !Throw it one time.  Throw uses the DISPLAYED attack power of a weapon, without any random variance - and in Excalipoor's case, this means it actually is like throwing a 100 ATK weapon!  The second is the Blue Mage: their Goblin Punch spell does an "attack" with some odd properties.  The relevant one here is that, again, it uses the displayed attack power - meaning a Blue Mage can ACTUALLY wield the 100-power fake as the weapon it pretends to be!
