How rolls land

Checked 01 Sept 2026 22:27 UTC

Every stat is rolled per copy. The ranges above are the two ends; this is where inside them a roll actually falls.

Reaching the top of a range means landing in the Mythic band — 1% of rolls. Each band decides where in the range a roll falls, as a fraction of that range.

Where inside a band a roll lands

What can be said is the band and its odds, which are listed above exactly as the game declares them.

How a roll applies

Range and SPA compound as pieces are added, so two of them are not the sum of their two numbers. Every roll is a percentage change applied after the piece is equipped. The final stat depends on the unit and its full build, so use the roll values as modifiers rather than treating them as finished stats.

What this piece changes

The wording below is as of Update 2.

This equipment slot holds two options and the game’s data does not say which of these two a roll grants, or whether a player can influence it. Both are shown as equals. Seeing the roll in game would settle it.

Crumble Away

A single slow applied on every upgrade becomes a table of different slows, one per attack in the rotation.

Before

Apply 20% Slow on all upgrades.

After

Apply Slow based on current attack: Explode - 20% Blast Away - 35% Twist - 50% Crush - 65%

Crumble Away: Inverse

A single slow applied on every upgrade becomes a table of different slows, one per attack, in the opposite order to the other option in this slot.

Before

Apply 20% Slow on all upgrades.

After

Apply Slow based on current attack: Explode - 65% Blast Away - 50% Twist - 35% Crush - 20%

Which of the two a roll grants

Both options are stored in full, and they carry the same per-attack values in reversed order. Nothing in the data selects between them, so neither is presented as the one you get and the two are not merged into a range.

What this passive is not in

What this passive does is stated above in the game’s own words, with its own numbers. It is in no number this site computes, because nothing in the data says when it fires and a reading of every equipment passive description finds none that fires unconditionally.

Which units can hold it

Salmon Sorcerer (Grade 1)

This is signature equipment, so the only unit it fits is the one it is bound to. A signature slot exists only on units whose rarity grants one, which is 53 of the 81 units the game publishes.

Equipment slots the game grants, by the unit’s own rarity — not the piece’s.
