The Finger of Fate

The Finger of Fate was a powerful weapon imbued with the blessings of Oa that paladin Dustin, son of Ogust wielded during his adventures. Its godly power passed away along its user and the now ordinary blade is being carried by Lina Iskaar.

Description
The Finger of Fate was a transforming weapon - its base shape being that of a knife - which, when activated, became a longsword made of holy light burning heavily on a strike. It was extremely deadly against the enemies of the Four and their underlings.

After the death of Dustin, the weapon lost its potency, turning into ordinary dagger, and was passed down to Lina by her mother, as per the will of the warrior.
