Flux

Flux is a legendary crown and face-mask that belongs to Frath Kulenov. The Promise Crew recovered Flux from the Matakai Nexus. It was previously worn by Yukiri Konine during the Age of Legends.

Powers
Flux's powers revolve around stealth and deceit.

Undetectable
Flux does not give off a magical aura per the spell Nystul’s Magic Aura. This effect may be activated or deactivated at will. You may also change Flux’s appearance to look like non-magical headwear.

Duplicity
At the end of each long rest, choose either Deception, Sleight of Hand, or Stealth. You gain advantage on those skill checks. You also learn the cantrip Minor Illusion.

Deceptive Charge
Whenever you succeed on a Deception, Sleight of Hand, or Stealth skill check; or you use Minor Illusion to deceive or distract, Flux gains 1 charge. When a target of Aura of Shadow succeeds on a Stealth check, Flux gains 1 charge.

Meld into Dusk
When you are in Dim Light or Darkness, as a Bonus Action you may expend 1 charge to teleport 60ft to an unoccupied space you can see in dim light or darkness. You then have Advantage on the next melee attack you make before the end of your turn.

Aura of Shadow
You can expend 3 charges to cast Darkvision or Pass Without Trace. When you cast Pass Without Trace with this feature, Flux maintains Concentration, not you. When you take damage, you must roll a concentration check as if you were concentrating on the spell.
