Tip for those struggling - Don't Neglect your One Dice!

[Osamaru]

For those struggling, a big tip I've yet to see is, DON'T NEGLECT YOUR ONE DICE!
This Relic is is INSANELY powerful, if used correctly. Not just for dealing with large enemy health, either.

After buying the upgrades, the Dice can be used on ANY number you see on screen. This includes your Gold value, the cost of items in shops, your mana value and even the numbers on Relics.

Got D20 One Dice charge but no gold to buy the shiny new relic in the shop you really want? Decrease the price and give yourself some gold.

Have a strong Buff that's about to run out? extend it for a while longer.

Like the effect of a Relic, but it takes to many Charges? (Looking at you, Chainstick) change it to 1 Charge to use!
Or change Bent spoon to +20 to your checks, and never fail to dodge again!

Honestly, decreasing enemy Health is the WEAKEST use for your Dice, and higher Ascensions really make you think on how to best use them.

How does The One Dice work? It says Permanently change to (d6 symbol). Usually, what it (appears to do is) rolls 1d6 after you choose a glowing number, then overwrites that number with the number rolled. But it appears that it can instead be used to overwrite a die symbol, e.g. causing that to become a d6 symbol instead (?).

For example, I used The One Dice Artifact on my The One Dice card thinking to get a permanent 5 or 6, but it just replaced the d6 symbol with another d6 symbol -- and also added Distortion.

Are there mechanics to figure out what The One Dice is going to roll before assigning it?

I noticed that The One Dice CANNOT be used on written-out numbers, nor does it work on some ability textboxes (for example cannot modify healing or damage of abilities such as Lifelink). Can it be used to modify cards currently in library or discard?

Are there specific details on how it works in unclear cases? For examples:

How exactly does it work on Library count and Discard count - is it literally scattering those cards 50%/50% to the other two locations (or stealing them, per the number rolled)?

How does it work on Mana - is the mana created random, or is the new mana never Colorless nor Void (always Red-Green-Blue-Purple)?

How does it work if I use a Temporary Buff to give my The One Dice Artifact extra charges, then spend those? (It appeared to remember and punish me by subtracting permanent charges from The One Dice Artifact after combat ended.)

How do I use The One Dice to "change my artifact to 1 charge to use" if I am rolling d20 - wouldn't it just as likely now require 20 charges?

Are there ways to use it to slow down the advancing purple mist?

The One Die only affects NUMBERS, not Die. The only cards I'm aware that can affect Die are Dicefy (which changes any die or number into a D8) and Tulpenmaine, which overrides any number or Die.

There COULD be others, but those are ones I know.

Define Written-out numbers, because I've been able to use to increase healing and the like and abilities. The only text it can't modify is text not directly accessible, such as Relics you already own, or cards in the Discard/library
You can use it ON the dicard or library, in that case it will randomly choose the number of cards you rolled, and move the remainder to the other pile (or take them from, if you rolled higher)

Totally random, as far as I can see. However, there's an ascension that makes it more likely to generate Chaos (purple) than anything. Not by much.

You just use it directly on the buff.

You have to use it when chosing the Relic at a rewards screen.
That's a risk you take. If you have a large One Die, you might be better off boosting its effect number, instead of the charge count.

Some differences, at least in the Demo:

Yes, you can use The One Dice Artifact on DICE too, not just on Numbers. Hold the mouse slowly over the Dice symbol, it creates an overwrite squiggle. Click. For example, a Relic that gives d4 extra mana capacity can be changed to provide d12 or d20 extra.

You can use temporary number buffs (such as adding 1d6) on available charges of The One Dice Artifact. (This works even though you cannot activate the artifact on itself.) Unfortunately, this appears to destroy any overcharges that you had accumulated on your The One Dice Artifact. What I mean is, the game will automatically reduce to 2 charges max at combat end, even if you entered battle with, for example, 11 charges.

You cannot use The One Dice Artifact on itself, even though this number is modifiable by other cards and effects.

When you use The One Dice on your discard or library, you end up getting a random (sometimes huge) number of extra cards directly into your hand - they don't all go to the other pile. A bad roll will also pull cards directly out of your hand.

When you use The One Dice on your mana count, you get additional random mana. But I've never seen it give uncolored (white diamond on grey disk) mana, nor give black-lightning-bolt mana (needed to power purify).

Never forget that you can use The One Dice on ANY visible number. Always experiment to see if you can find more things and methods to abuse The One Dice. The knowledge is really power in this game.

So, to answer your questions: First off, if you can use The One Dice on a number, that means it will have a controllable, consistent effect. Remember that The One Dice makes that number into the exact number you rolled. That is a thing that matters.

I highly discourage determining the exact mechanics of how this works via wiki or forums since experimenting and finding new things with it is very fun. But if you want some exact answers:

The Draw Pile, for instance: If you roll a number higher than what is in the draw pile, cards from the discard pile will flow onto the draw pile until it is the number that was rolled. I have not seen it but if the discard pile is emptied, it will probably take cards from your hands too. (I want to know what would happen if you roll a 20 when your deck has less than 20 cards. Will it generate cards? A interesting thing to experiment on later) If you roll a lower number, however, the cards in the draw pile will go into your hand, and some into the discard pile, until the draw pile has cards equal to the number The One Dice rolled. That means if you roll a 1 on a 30 cards big draw pile, you better know that most of them are going into your hand. The number seems to be something like %50 into your hand and %50 onto the discard pile, and if you reach the hand size limit, all the remaining ones that would go to your hand will flow onto the discard pile.

Rolling a number higher than the discard pile number will discard some cards in your hand, and a lower number will put the discarded cards onto the draw pile.

You can reroll Relic charges. You can reroll The One Dice relic charge with the card version, to basically get free charges. The charges you get this way will stay like that after combat too.

You will later get the ability to reroll numbers on an Event screen. This is undoubtedly a broken ability if you learn how to abuse it.

The ability to use The One Dice on Shops and Loot Screens is also extremely powerful. The usage of that and the abuse methods are very obvious too...

You can reroll the numbers visible on a non-active relic, like the "This relic can only activate x times on battle" on your starter relics. It will not permanently change that stat on the relic, but it will generally make you get more activation times on that specific combat instance. Pay attention to what is the visible number on a relic is, and see if rerolling it in the combat would be beneficial. To permanently change a number on a relic, you need the "Loot Screen" upgrade.

You will get void mana and... the black lightning bolt (I don't remember the name either lol) too while gaining mana through the One Dice. You might just not have hitten a high number while using the dice on the mana pool, or might have just gotten unlucky. The extra mana you gain via this will always be random. And you must not forget that this also increases your Mana Pool capacity too.

You found out a thing and seemingly given a false answer, so let me give a better answer. Spoilers for everyone except the guy I'm replying to, this is a thing that is better discovered naturally. You found out that The One Dice can also interact with dice numbers(aka things like "Do (D6) damage", etc.). After your first run or your second run, you can unlock the ability to upgrade The One Dice, to a maximum of a (D20). So what happens when you targeet a (D6) number on a card or a relic with your higher number The One Dice, like a D20 one? It will replace that dice number with the one your One Dice's level is. That means the card would become "Do (D20) damage".

This mechanic has a lot of certainly broken applications. On a resting area, you have a choice between gaining 20 hp or gaining (D6) charge on your One Dice relic. You better believe that you can use 2 charges to make that (D6) into a D(20) and get a LOT of charges for basically free. Changing a dice number into D20 with your One Dice has no RNG, it is more reliable to do and generally way more beneficial to do. The "Do (D6) damage to a enemy (D6) times" card comes to mind. The upgraded version of that card with the times number changed to (D20) is broken. If you chance upon an event that can get the "Distorted" effect deleted, you can change the damage too. Stack a few luck modifiers and it will straight up one shot all bosses with some extra boosts.

Do not forget that rerolling a already distorted Card will give it [Glitchy]. The next time you use it, it will become broken, and the broken card is unusable in most situations.
