Alfred's illusionary gambling Cones

As an action you touch a willing creature and hide it under three gambling Cones. Until the spell ends, the gambling Cones move with the creature and after any action on the hidden creature turn the cones shuffle position so it's impossible to know under which cone the creature is hidden. You can use your action to dismiss the illusory gambling cones.

Each time a creature targets a gambling cone with an attack during the spell's duration, roll a d20 to determine whether the attack instead targets one of the empty cones.

If you have three gambling cones, you must roll a 6 or higher to change the attack's target to a duplicate. With two gambling cones, you must roll an 8 or higher. 

A gambling cones AC equals 10 + your Dexterity modifier. If an attack hits a gambling cone, the cone is destroyed. A cone can be destroyed only by an attack that hits it. It ignores all other damage and effects. If an attack hits the hidden creature, the gambling cones shuffle again to hide it. The spell ends when two cones are destroyed. 

A creature is unaffected by this spell if it can't see, if it relies on senses other than sight, such as blindsight, or if it can perceive illusions as false, as with truesight.
