How to calculate Crit Chance on Melee weapons?

[dead.rabit]

I want a red crit nikana prime (20% base crit chance). The wisdom of the internet tells me I need Blood Rush (+165%) & True Steel (+60%) to achieve this, anything over 100% crit chance is your red crit chance and mods multiply (not add) to the base crit chance. I took the formula from the wiki: http://warframe.wikia.com/wiki/Critical_Hit

0.2 * (1 + 1.65 + 0.6) = 0.65 * 100 = 65% Critical Chance? So my logic has gone wrong somewhere, can anyone point it out for me?

By my logic if I were to put all 4 Crit Chance mods in, I'd still only come up with a 91% Critical chance.

Thank You.

The point where you got it wrong is, how Blood Rush works.

i think you are wrongly calculating blood rush, m no expert tho. maybe try warframe-builder to see. blood rush stacks with your combo, so each combo level adds to your crit chance.

blood rush is multiplied by your combo meter.

with true steel you got 20x1.6=32%, true steel is still importent though, because it stacks with blood rush which means that those 12% will turn into a lot more down the line.

at 1.5 combo you will have 1.5 (combo)x1.65(blood rush)=2.475x critical chance, which translates to 247,5% critical chance, that means that a nikana prime with true steel at 1.5 combo will have 111% critical chance, only 11% to red crit, but at 2 combo you will have 143% crit chance and so on, your critical chance increases greatly with time, and you get greater combos within seconds with a good build, feel free to ask if anything isn't clear here.

You should read the wiki article for critical chance carefully...

Red critical hits are guaranteed at 200.1% critical chance and higher.

100.1% - 200% critical chance guarantees yellow critical hits and a chance for red critical hit. (Scales with %)

 

P.S. Also read the Blood Rush mechanics as mentioned...

aha, so I made two mistakes.

1. Blood Rush Crit Multiplier is added after other mods to critical chance
2. I thought blood rush would add up to 165% crit chance, where actually it's the bonus crit chance at 2x Combo, at 3x combo it'll add 330% crit chance

I love blood rush already :)

Thankyou all, this has been very helpful.

Fun fact, if you get over 200% crit chance, your red crits will actually do more damage than expected, scaling indefinitely for each 100% crit chance past 200%

I like to call these "super crits." Other than melee weapons with blood rush, guns like the Amprex can get over 200% crit chance with a good enough riven.

Super crits? Really? How intriguing... I've never heard any mention of this, but it sounds amazing. To be fair, I've never had a weapon reach more than 175% crit chance :P How much does the damage scale compared to regular red crits?

If regular crits multiplied your crit multi by 1x and red crits at 101%-200% crit chance multiplied it by 2x. Then super crits at 201%-300% will multiply your crit damage by 3x, and 301%-400% by 4x and so on. So say you have a melee weapon that  normally has a crit multi of 4.4x, that's 8.8x on red crits, but with super crits, it can be 13.2x or 17.6x and beyond
