The Dice Goblin

your intense love for dice has pushed away your family, your friends, your life. the dice contain you, you roll you. Your heart has been so consumed by the dice that your soul now has a coat of resin, plastic and occasionally metal. In your lowest moments, you sought more dice. more power, more chances, and the world heard your prayers. but your prayers did not rise to the heavens, instead they were dragged to the underworld, like a weighted die, held down by your sins. The dice goblin found you and granted you new power. staggering around with a pouch of chances numbers branded around his neck, he reaches out a hand to you. you clasp it, and with that motion a deal is formed.

The Goblins Chest

As soon as you become a disciple of the goblin, you are overwhelmed with his strength. You gain access to an ancient vault, and all the Polyhedral treasures that lurk within.
2 times per short rest, you may reach within his chest and pull forth from it die. You use this to replace any roll you just did, and it must be used. This must be used immediately after rolling the die, before you hear the result.
You gain 3 uses at 3rd level, 4 at 8th level, 5 at 14th level and 6 at 18th level.

Four Edged Skin

when you reach level 6, Your strongest die, the four sided die, manifests as apart of your body. You can use your reaction to gain a +3 to AC when you get attacked by a physical or magical attack. E.g. Longsword, Fire Bolt

Dice Tower

When you reach level 10, your bond between you and the Dice Devil manifests into something physical. You can now summon a tower with which you and your allies may reside in. The tower provides you with 5 bedrooms, a kitchen, a living room and a war room. It is proportionate to the players height, with each room being 2 feet taller then the characters height and and its total height being 9 times the players height (each room plus 2 feet per). The tower's size is 3 meters by 3 meters. It's decorations are decided when you reach this level based on your characters personality, and it acts as your lair. It lasts for 24 hours, and dispels all magic used by creatures below the players level. It has a simple lock on the door with an AC of 17 and the counter-spell primed to block magical attack which, if broken, resets automatically when the tower is recast. When the time runs out, the tower disappears to a safe spot in the Ethereal plane, where time stands still and all creatures and living things do not age. When they are returned to the material plane, it feels as though time has not moved. Everything inside is stored. On top of that, if anyone is inside the tower when the time runs out, they are spat out of the tower unless the player and the creature choose for them to be teleported away with it. The tower can be summoned at any time, requiring 1 minute of concentration, and can be disappeared instantly. It can only be summoned again after 2 hours, and only one can exist at a time.

Tray of Weighted Dice

You gain this feature when you reach level 14. Now that you're beginning to understand the intricacies of the dice, the Goblin devil Yorn has blessed your hands. He has taught you the true technique for rolling the dice, and you have gained a power beyond your wildest beliefs. You now turn your whole field into your dice tray. Once per long rest, you enter a trancelike state for 3 minutes, where you create an ethereal stage. Your hands become locked together, shaking ever so slightly, almost as if there's a die in there you're about to roll. The heart of the dice imbue you and your allies with blessings capable of changing fate and saving them from the tragedies pre-determined to befall them.

the stage has a radius of 100 meters, and you can choose up to 5 allies for it to affect. While maintaining the stage, you cannot use any actions except simple movement and free object interaction that doesn't require your hands. All Ability Checks, Attacks Rolls (Not damage), Saving Throws and Death Saves made by you and the allies now have a minimum equal to your passive charisma plus their deception modifier.
