Wyrdweaver

At 1st level, you learn to shift the weaves of fate to aid allies and hinder foes. When a creature you can see within 60 feet of you makes an attack roll, ability check, or saving throw with advantage, you can use your reaction to expend one probability die and force that creature to make a Charisma saving throw against your spell save DC, adding the probability die to the DC. On a failed save, the creature loses advantage on that roll, and one friendly creature you can see within 60 feet has advantage on its next d20 roll of the same type the creature used (attack roll, ability check, or saving throw).

Starting at 1st level, you gain the ability to manipulate probability. You have a pool of d6s that you spend to fuel your patron abilities. The number of probability dice in the pool equals 1 + your warlock level.
You can use these dice to turn the odds in your or your ally's favor. When you or a friendly creature you can see within 30 feet of you makes an attack roll, ability check, or saving throw, you can use your reaction to expend probability dice from the pool, rolling the dice and adding the total result to that roll. The maximum number of dice you can spend at once equals your Charisma modifier (minimum of one die). Your pool regains all expended dice when you finish a long rest.
When you reach certain levels in this class, the size of your probability dice increases: at 5th level (d8), 11th level (d10), and 17th level (d12).

At 6th level, you can channel dark power from your patron to empower your attacks and spells. Once on each of your turns, when you hit a creature with an attack, you can expend one or more probability dice, up to half your Charisma modifier (minimum of 1), and add the probability dice to the attack's damage roll.

At 10th level, you learn to redirect magical energy, converting the power to restore your pool of probability dice. When a friendly creature you can see within 30 feet of you takes acid, cold, fire, lightning, or thunder damage, you can use your reaction to take the damage instead. You halve the damage you take as your probability wellspring absorbs some of the magical energy. For every 10 damage prevented in this way, you regain one expended probability die. You can't regain more than half your maximum probability dice from this feature. Once you use this feature, you can't use it again until you finish a short or long rest.

Starting at 14th level, your very presence spins probability. When a creature you can see within 60 feet of you makes an attack roll, ability check, or saving throw with advantage, you can use your reaction to force the creature to make a Charisma saving throw against your spell save DC. On a failed save, the creature loses advantage on the roll and has disadvantage on it, and you have advantage on one d20 roll of your choice within the next minute. Once you use this feature, you can't use it again until you finish a short or long rest.
