Details on both how Criticals are procced and are scored.

$$critchance = tech_e * \frac{3}{100\,000} + bondboard + \sum_{Skills}skill + \begin{cases} 0.15 & \text{if Tech is the highest stat} \\ 0 & \text{otherwise} \end{cases}$$

$bondboard$: The Critical Chance bonus from the Bond Board of the character

$skill$: The percentual effect of an active Critical Chance buff/debuff

As a rule of thumb, to estimate the base Critical Chance from Tech, you can divide it by 1000. Every 1000 Tech results in 3% Crit Chance.

The condition for the 15% bonus, commonly known as Crit Profile or Critical Sense, uses the card's defined stat distribution. Technique must be the single highest stat, if tied with another stat the bonus will not apply. The easiest way to check in game is checking the nodes in the card's training tree - if the increase per node is bigger for Technique nodes than for the other two stat nodes, the card has crit profile. Whether a card receives this bonus or not is hardcoded in the game's database¹⁾, and will not change even if any step of the stat calculation would raise another stat enough to be higher than Tech.

The $\frac{3}{100\,000}$ factor comes from the calculation $\frac{tech_e}{10\,000} * \frac{3\,000}{10\,000}$. 3000 is Constant 33, and is the deciding factor of how much Tech is converted into Crit Rate.

$$critpower = (1.5 + bondboard + \sum_{Skills}skill) \cdot accs$$

$bondboard$: The Critical Power bonus from the Bond Board of the character

$skill$: The percentual effect of an active Critical Power buff/debuff

$accs$: Sum of Base Critical Power Accessory effects (Hairpins and Bangles). See Accessories for Skill Effect calculation

To do: Is there a difference between Base Crit Power and non-Base Crit Power skills? Are all of them additive?

To do: Is the Bond Board bonus multiplicative or additive?

(Editor's note: at least this is easier to test than pseudorandom crit chances woo)

Depending on a unit's base Crit Power (only the base 1.5 plus Bond Board bonus), a different effect is shown for the “CRITICAL” rating popup.

The default effect is a blue-purple “CRITICAL” popup with unfilled lightning icons. Big stars are emitted as particles.

When one Crit Power node is unlocked on the Bond Board (base Crit Power of at least 1.5001), the Level 2 effect is shown. The lightning icons are now filled, and small triangles are added to the particles.

Finishing the Level 100 Bond Board (base Crit Power of at least 2) will show the Level 3 effect, changing the color to green-blue and the icons to double lightning bolts. The particle effects add large, spinning, unfilled triangles. Additionally, a little zoom animation is applied to the rating.

Level 1 (0% Board bonus)	Level 2 (0.01% Board bonus)	Level 3 (50% Board bonus)	Level 4 (150% Board bonus)

The max level effect, Level 4, can be activated by reaching a base Crit Power of 3 or more, however, there were never enough Crit Power nodes on the Bond Board to make it possible to reach this.
