Lambent Viper

''A small glowing orb, about the size of a grapefruit rests in your hand. Giving it a squeeze is met with resistance, almost hard but not quite solid. Waving the orb around lets loose a trail of arcance energy that lingers for a moment before vanishing.''

Whip, no attunement
The Lambent Viper is a whip that deals 1d6 radiant and 1d6 poison instead of 1d4 slashing damage. When rolling damage, and both d6s come up as 1s, you may treat it as if you rolled 6s on those dice instead.
