Lugh's Spear

Origin
Lugh's spear, according to the text of The Four Jewels of the Tuatha De Danann, was said to be impossible to overcome, taken to Ireland from Gorias. There are two incantations added to the spear. Saying 'Ibar' would allow the spear to always hit its mark and 'Athibar' would cause the spear to return to Lugh's hands.

Effects
Whoever uses the spear is undefeatable in battle however the cockiness that derives from being undefeated lasts after putting the weapon down. This cockiness could lead to disastrous risks like taking on a bigger opponent without the spear thinking you could still win.
