Just making this so if I need to find the formulae i can get to it through my profile/bookmark, obviously also use this if you need to! (Ignore the examples if they aren’t needed, they are only there for if the formulae are unclear).
Though the Character Sheet displays your crit chance of all types, it only factors in global and generic increases, not factoring in skill trees and things like “crit chance for lightning skills”.
Minion critical strike chance is calculated in the exact same way as players, so this formula works to calculate a minions crit chance as well. (minions also have 5% base crit chance).
Calculating Critical Strike Chance:
Formula:
x * (1 + y%) = Critical Strike Chance
Key:
x = Base crit chance + Added % crit chance from all sources.
y = Increased % crit chance from all sources.
Example:
If you had 5% added crit chance from your base crit chance, and +10% added crit chance from source 1, x would be 5 (base crit chance) + 10 (source 1). Meaning x = 15
If you had 100% increased crit chance from source 1, and 50% increased crit chance from source 2, y would be 100% (source 1) + 50% (source 2). Meaning y = 150%.
calculation with 15% total added crit chance and 150% total increased crit chance:
15 * (1 + 150%) = 37.5% Critical Strike Chance
Calculating with multiplicative increases:
Formula:
x * (1 + y%) * (1 + m1%) * (1 + m2%) = Critical Strike Chance
Key:
x = Base crit chance + Added % crit chance from all sources.
y = Increased % crit chance from all sources.
m = More % crit chance from a single source. (Number differentiates sources).
You can have more than 2 sources of “more”, you would just consider those m1, m2, m3… etc and they follow the same rules as the 2 sources used.
Example:
If you had 5% added crit chance from your base crit chance, and +10% added crit chance from source 1, x would be 5 (base crit chance) + 10 (source 1). Meaning x = 15.
If you had 100% increased crit chance from source 1, and 50% increased crit chance from source 2, y would be 100% (source 1) + 50% (source 2). Meaning y = 150%.
If you had 20% more crit chance from source 1, and 30% more crit chance from source 2, meaning m1 = 20%, and m2 = 30%.
Calculation with 15% total added crit chance, 150% total increased crit chance, 20% more crit chance and 30% more crit chance:
15 * (1 + 150%) * (1 + 20%) * (1 + 30%) = 58.5% Critical Strike Chance
If I have gotten any calculations wrong or could simplify any of them please let me know and I will edit this post ASAP. Hope this helps and have a good day! <3
EDIT: Reformatted the formulae and fixed the “more” formula which I believe was incorrect. Big thanks to PvtVlad.
