Amulet of Fate Sealing

You may attune to this item by spending 10 seconds to concentrate on it, instead of attuning to it on a short rest. You may also attune to this item up to three times, for every extra time you attune to it you gain the effect this item provides an additional time, like you attuned to a second item with the same effect.

When you attune to this item, you roll a d20 and store the result. Until you finish a long rest, you can use this roll in place of any other d20 roll before you actually roll the dice. If you finish a long rest and you still didnt use the result, you take 1d6 psychic damage for each stored result you didnt use, which increases by an additional 1d6 for each unused result, up to a maximum possible of 9d6 psychic damage if you had 3 of them stored.

You may not remove attunement from this item until you finish a long rest or it is destroyed. If you throw away this item and abandon it, it will teleport in an unoccupied space within 5ft of you every time it gets further than 60ft from your character. At the end of every long rest you lose attunement to the item.
