Crit Value: The combined effectiveness of crit rate (valued twice) and crit damage. Example: A echo with 6.3% crit rate and 15% crit damage would have a crit value of 27.6 (6.3% rate * 2 + 15% damage) out of the possible 42 (10.5% rate * 2 + 21% damage).

This rating is only visible on characters that include crit stats in their weighted stats. Tiers: The segmentation on stat bars displayes the different possible roll values. The higher the tier of the roll, the more segments are highlighted. Possible substats in Wuthering Waves are pre-determined (meaning, for example, you can't roll 6.7% ATK% — only 6.4% or 7.1%) and heavily weighted (the lowest being almost 2.5x more likely to appear compared to the highest).

More information can be found in the "Substat Distribution" table below. Weighted: The total percentage value of all stats weighted by the listed character-specific modifiers. This rating is displayed in a letter-based format for easier understanding. Echo Value: The resulting stats, adjusted by (the accummulative) probability of the given tiers, (slightly) increasing the value of higher rolled stats instead of using a equal distribution.

Disclaimer: While character-specific weighting is applied, secondary requirements like energy regen and overall crit ratios are not checked and can result in performing below expectations. Always use this stat with your current in-game crit scoring and character-specific secondary requirements (like Energy Regen) in mind.
