How to Get and Use Variable Dice in Honkai Star Rail (Reroll Your Relic Rolls)

There is a special kind of relic heartbreak in Honkai Star Rail: the piece with perfect substats on paper — CRIT Rate, CRIT DMG, Speed, ATK% — where every enhancement roll then lands in the wrong line. Variable Dice exist for exactly that relic. Added in version 3.0 alongside Wishful Resin, they do not craft anything new; they give a finished relic one more shuffle of the dice.

What a Variable Dice actually changes

When a relic levels up to +15, its enhancement rolls distribute among its four substats. A Variable Dice randomly redistributes those rolls across the same substats. Three limitations define the item:

• The relic must be at level 15 — there is nothing to redistribute before every roll has landed.
• The dice cannot change which substats exist on the relic. If the piece has flat DEF, flat DEF stays.
• There is one exception: a substat that was newly added at level 15 (the fourth line that appears on a 3-substat relic) can be rerolled into a different substat entirely.

How to use one

Open the relic, select the Variable Dice option, and the game shows you the new distribution before anything is final. You can accept the new rolls or keep the old ones — a genuine safety net, since a redistribution can just as easily make things worse. But be clear-eyed about the cost: the dice is consumed even if you keep the original rolls. The preview protects your relic, not your item.

Where to get Variable Dice

• Nameless Glory: the premium tier of the Nameless Honor battle pass includes one Variable Dice per version.
• Craft them: the Omni-Synthesizer can make a Variable Dice for 3 Self-Modeling Resin each, with no crafting limit. 'No limit' is theoretical, though — Self-Modeling Resin is one of the scarcest items in the game, so every crafted dice is three custom-main-stat relics you chose not to make.

When a reroll is worth it

The maths favours one clear case: a relic whose four substats are all stats your character wants, but whose rolls clustered on the least useful of them. Picture a damage dealer's piece with CRIT Rate, CRIT DMG, ATK% and Speed, where four of five rolls slid into ATK% — a redistribution has a real chance of moving rolls into the Crit lines, and almost no way to make the piece useless.

Skip the dice when a substat itself is dead (the dice cannot remove it), or when the relic is merely fine rather than nearly perfect. With supply this thin — roughly one per version unless you burn Self-Modeling Resin — Variable Dice are a scalpel for your single best almost-there relic, not a slot machine for the whole inventory.

It also helps to think about what the dice really sells you: not better odds on average — a random redistribution is as likely to hurt as to help — but optionality. Because you can reject the outcome and keep your current rolls, the dice only ever 'fires' when it improves the piece. The true price is the opportunity cost: that dice, or the three Self-Modeling Resin it took to craft, is gone even when you walk away with the relic you started with. Spend it where an improvement would be felt in every fight — your main damage dealer's core pieces — and nowhere else.
