Skirnir's Wand

Cannot be auctioned, traded, or bazaared, but can be delivered to a character on the same account.
Can be obtained as a random reward from the Gobbie Mystery Box Special Dial and similar sources.

In Norse mythology, Skírnir is Freyr's messenger and vassal. His name means "the shining one". He was sent as a messenger to Jötunheimr to conduct Freyr's wooing of Gerðr on condition of being given Freyr's sword as a reward. He was also sent to the dwarfs to order them to make the chain Gleipnir for binding the wolf Fenrisulfr.

There is no indication he had a wand but because his name means "the shining one" it could explain the light bonuses as well as the divine magic skill. Also as a messenger for a god it may also explain the boosts in charisma, mind and intelligence.
