A glove that emanates a dark aura, the Royal Grip is a powerful artifact. It slips onto the left hand of anyone who wishes to wear it. Once it's on, tendrils envelop the forearm of the bearer, making it a mostly permanent addition to their body. If the owner dies, the glove returns to its original form. It has a mind of it's own, becoming a whisper in the back of the mind of the bearer. It steers them towards evil, typically causing a war of emotion within them. Its main objective tends to be forging the bearer into a ruler, sometimes of the entire world. Its abilities make said objective very possible...

Attunement Perk: Grasp of the King
                    You can make lashing tendrils of energy ingrain themselves within an enemy using this item. This deals 1d6 Necrotic damage, and saps 1d4/2 (rounded up) of their strength. Said strength is given to the user, empowering them until combat ends. If an enemy's strength is lowered to 0, the tendrils do something... Odd. The dark aura seeps into the soul of the target, and they are transform. Their body becomes enveloped permanently in darkness, and they gain a single, white sphere around where their face used to be that seems to act like an eye. The user takes full control of them, as if they were completely imposing their will on the target. The user can order them into a demiplane of the glove's creation, and can summon them back at any time, in any place as long as the place is on the same plane. If the user manages to place their hand that bears the glove on the head of another being, they are also turned into those strange creatures. The only weakness of the glove is that it causes the user to be utterly susceptible to Radiant damage, taking x4 damage from that type of damage.
