Centaur of Attention

You may reroll any results stored on Centaur of Attention, even those you chose not to reroll on previous turns.

To get the largest bonus from the last ability, you want all five dice to have the same result. It doesn't matter what result that is. The value of X is the largest number of dice that match, not what number they're showing. For example, if your five results are 1, 1, 3, 3, and 4, Centaur of Attention would get +2/+2.

Each die is identified by the number of faces it has. A six-sided die is a die with six equally likely outcomes: 1, 2, 3, 4, 5, and 6. The roll must be fair. Although physical dice are recommended, digital substitutes are allowed except in cases where the physical die is required for the effect.

If an ability triggers "whenever you roll a die," it will trigger whenever you roll any die, including the planar die. This is a change from previous Un- rules. Some abilities use the result to determine part of the effect. If you get a non-numerical result (currently just the planar die, but the future is long), that part of the effect won't do anything.

If a die is rerolled, the original roll essentially never happened: it doesn't cause any abilities to trigger, and no effect that cares about die rolls will consider it.

Something in the game must tell you to roll a die. If you roll a die for any other reason (to simulate a coin flip, to choose pizza toppings, to create alternate timelines), that roll doesn't count.
