Nimbus, Thunderbird Staff

Requires Attunement:
If you use this Staff to make a
Melee Weapon Attack, the attack deals
an additional +1d6 Lightning Damage.
While attuned to this item and using it
as an Arcane Focus you may reroll 1's and 2's
on damage dice for Lightning Elemental Spells
and Melee attacks (One reroll per die, you keep
the second result).
