A Faster Hit Recovery bonus.
Faster Hit Recovery (FHR) is a coefficient that increases the speed of recovery from being stunned. A character gets stunned when a monster successfully damages him/her more than the stun threshold allows.
Diablo I[]
Hit Recovery is in its most basic form in Diablo/Hellfire, with almost every class suffering from the same stun threshold. Given the high damage in later levels on Hell difficulty, nothing can be done to prevent stunning, short of having a high Defense. As such, items that offer a faster hit recovery helps to prevent a stunlock on the hero.
As noted above, while almost everyone has the same stun threshold, one differs. The Barbarian from Hellfire has a slightly higher stun threshold per level than the rest of the classes, to fit with his axe specialization.
From top to bottom:
- Barbarian stun threshold: 1.25 points of damage per level.
- All other classes: 1 point of damage per level.
Diablo II[]
All characters share the same stun threshold in Diablo II/Lord of Destruction. If a hit from a monster deals damage greater than 1/12th of a hero's maximum Life, he/she will be stunned. Each character has a base hit recovery value. This is not a base hit recovery rate, but the value is used to calculate the hit recovery rate. The hit base of the characters are as follows:
| Amazon | 6 |
| Assassin | 5 |
| Barbarian | 5 |
| Druid | 7 |
| Werewolf | 4 |
| Werebear | 5 |
| Necromancer | 7 |
| Paladin | 5 |
| Sorceress | 8 |
| Rogue Archer | 6 |
| Desert Mercenary | 8 |
| Iron Wolf | 9 |
| Barbarian Warrior | 5 |
The standard animation speed is 256 except in the case of the human-form Druid wielding one handed weapons (248), Werebear-form Druid (184), and a Paladin using two handed weapons (192).
The calculation to find Effective Faster Hit Recovery (EFHR) is:
EFHR = [FHR x 120 / (FHR + 120)] (rounded down)
The calculation to find the hit recovery frames is:
Hit Recovery Frames = {256 x Hit Base / [Animation Speed x (50 + EFHR) / 100 (rounded down)]} (rounded up) - 1
Faster Hit Recovery breakpoints[]
There are 25 frames per second, so as the Faster Hit Recovery increases, the frames decrease.
Since frames of animation cannot be further divided into fractions, this creates "breakpoints". You will not see any change in Faster Hit Recovery until you pass the next breakpoint. This means that an Amazon with 31 FHR is effectively equal to one with only 20.
As one frame is a mere .04 seconds, it may not even seem worthwhile, however in practice, even single frames can make a noticeable difference.
