Deck of Illusions

A Deck of Illusions is a box containing a set of parchment cards. A full deck has 34 cards, but one found by adventurers is usually missing 1d20 minus one cards.

Description
The owner of the Deck of Illusions can use an action to draw a card at random and throw it onto the ground at a point within 30 feet of them. If the card is not drawn randomly, it has no effect.

When a card is thrown, an illusion of the creature or creatures will form over the thrown card and remain there until dispelled. An illusory creature appears real, of the appropriate size, and behaves believably for that creature, but cannot do damage. While the owner of the deck is within 120 feet of the illusory creature and can see it, they can use an action to move the creature magically anywhere within 30 feet of the card.

Any physical interaction with the illusory creature reveals it to be an illusion, because objects pass through it. Someone who uses an action to visually inspect the creature can identify it as illusory with a DC 15 Intelligence check, at which point the creature appears translucent to them. The illusion lasts until the card is moved or the illusion is dispelled. When the illusion ends, the image on its card disappears, and that card can't be used again.

History
At one point in time, before the start of the stream, Tiberius acquired a Deck of Illusions and, possibly, once drew the nine of spades, summoning an illusory troll. He first used it to attract duergars from their camp, toward the Hallucinatory Terrain and the chasm behind it, throwing three cards near the edge: the ace of spades (lich in golden red robes, with gnarled gold crown and glowing blue eyes), the jack of spades (human veteran holding a big old longsword and armored up in scalemail), and a joker (illusion of Tiberius).

Tiberius' second pull was in the basement of the Platinum Sanctuary, cleaning out the space for the Horn of Orcus from phase spiders, he drew two card from the deck: a joker and the ten of hearts, creating a female version of himself and a cloud giant to distract the platinum golems, guarding the sanctuary.
