The scaling of secondary stats and their diminishing returns underwent several changes after Battle for Azeroth, primarily due to the borrowed power system at the end of that expansion, which allowed players to stack enormous amounts of secondary stats. To address this, Diminishing Returns were introduced for Haste, Crit, Versatility, and Mastery. To learn more about each Stat click here.
Mastery in itself is a special case since every Class converts Mastery rating at a different ratio depending on the class specialization.
Secondary Ratings
Below is the amount of rating needed for each secondary stat to achieve a 1% flat increase before any diminishing returns or penalties are applied at level 70 and 80.
| Stat | Effect | Rating needed at Level 70 | Rating needed at Level 80 |
|---|---|---|---|
| Haste | 1% Haste | 170 | 660 |
| Crit | 1% Crit | 180 | 700 |
| Versatility | 1% Damage done 0.5% Damage taken reduce | 205 | 780 |
| Mastery | 1% Mastery | varies by specialization | varies by specialization |
Brackets
Previously, stats grew linearly, meaning a 1% increase would directly add 1% to your current percentage. Nowadays, there are different brackets that serve as diminishing returns to all secondary stat increases depending on the bracket you're in starting at 30% with the exception of Mastery since different specializations use different conversions. These penalties range from 10% less stats from rating to up to 100% less.
The penalty brackets displayed in absolute rating look like this:
| Stat | Penalties and absolute ratings at level 70 | |||||
| -10% | -20% | -30% | -40% | -50% | -100% | |
| Haste | 5100 - 6800 | 6800 - 8500 | 8500 - 10200 | 10200 - 11900 | 11900 - 34000 | >34000 |
| Crit | 5400 - 7200 | 7200 - 9000 | 9000 - 10800 | 10800 - 12600 | 12600 - 36000 | >36000 |
| Versatility | 6150 - 8200 | 8200 - 10250 | 10250 - 12300 | 12300 - 14350 | 14350 - 41000 | >41000 |
| Mastery | 5400 - 7200 | 7200 - 9000 | 9000 - 10800 | 10800 - 12600 | 12600 - 36000 | >36000 |
| Stat | Penalties and absolute ratings at level 80 | |||||
| -10% | -20% | -30% | -40% | -50% | -100% | |
| Haste | 19800 - 26400 | 26400 - 33000 | 33000 - 39600 | 39600 - 46200 | 46200 - 132000 | >132000 |
| Crit | 21000 - 28000 | 28000 - 35000 | 35000 - 42000 | 42000 - 49000 | 49000 - 140000 | >140000 |
| Versatility | 23400 - 31200 | 31200 - 39000 | 39000 - 46800 | 46800 - 54600 | 54600 - 156000 | >156000 |
| Mastery | 21000 - 28000 | 28000 - 35000 | 35000 - 42000 | 42000 - 49000 | 49000 - 140000 | >140000 |
Note that each diminishing return or penalty for secondary stats is only applied to the rating that crosses each threshold.
Percent gains from spells like Berserking, Bloodlust, or Heroism don't count towards the penalty. Only raw rating gains are affected. Which means that anything that gives you raw rating gets penalized.
Example
At Level 70, 1% Haste is equivalent to 170 rating. This means you can have up to 5100 Haste (30%) without any penalties. If you now equip an item that would normally increase your Haste by 1020, your actual Haste percentage would only go up to 35.4% instead of the expected 36%.
Tertiary Ratings
Below is the amount of rating needed for each tertiary stat to achieve a 1% flat increase before any diminishing returns or penalties are applied at level 70 and 80:
| Tertiary Stat | Effect | Rating needed at level 70 |
|---|---|---|
| Avoidance | Reduces AoE damage taken by 1% | 72 |
| Leech | Heals the player for 1% damage and healing done | 148 |
| Speed | Increases movement speed by 1%. | 50 |
| Tertiary Stat | Effect | Rating needed at level 80 |
|---|---|---|
| Avoidance | Reduces AoE damage taken by 1% | 544 |
| Leech | Heals the player for 1% damage and healing done | 1020 |
| Speed | Increases movement speed by 1%. | 170 |
Brackets
All tertiary effects are also affected by diminishing returns that take effect when a specific threshold is crossed. The reduction begins at 10% and ramps up at 15% and 20% and stops at 49%.
The penalty brackets displayed in absolute rating for tertiaries look like this:
| Tertiary Stat | Penalties and absolute ratings at level 70 | |||
| -20% | -40% | -60% | -100% | |
| Avoidance | 720 - 1080 | 1080 - 1440 | 1440 - 3528 | >3528 |
| Leech | 1480 - 2220 | 2220 - 2960 | 2960 - 7252 | >7252 |
| Speed | 500 - 750 | 750 - 1000 | 1000 - 2450 | >2450 |
| Tertiary Stat | Penalties and absolute ratings at level 70 | |||
| -20% | -40% | -60% | -100% | |
| Avoidance | 5440 - 8160 | 8160 - 10880 | 10880 - 26656 | >26656 |
| Leech | 10200 - 15300 | 15300 - 20400 | 20400 - 49980 | >49980 |
| Speed | 1700 - 2550 | 2550 - 3400 | 3400 - 8330 | >8330 |
Note that each diminishing return or penalty for tertiary stats is only applied to the rating that crosses each threshold.
