Affinity. How does it work.

[Schrödinger]

So. 500+ hrs in MHW.

A year after it's release I got Rise finally. And I don't remember if I ever knew, but is affinity as straight-forward as it comes off or not. Does 10% affinity = an additive 10% chance per hit to crit? So getting lets say, 15% from armor, 25% from a weapon, would equal a 40% crit chance? Or is there a very complicated mathematical formula to find your true crit chance? For me, anything besides the most basic algebra is basically wizard magic.

1. Yes
2. Yes
3. There is some exception how it works. For example with WEX do lets day you have 50% crit chance from weapon. Weakness gives you another 30% crit but it only works if you hit monster weakness spots. So the total 80% if weak spot is hit otherwise its 50%.

So it's completely straight-forward, and if I have 40% affinity I have a 40% crit chance?
But there's also some rocket science behind it for those that know wizardry?

Ah saw your edit, thank you very much.

Affinity is straight crit chance. All sources of affinity are added for a total. Some sources are situational, such as an ability activating under specific circumstances to give a temporary boost to affinity.

Keep in mind that affinity can go below 0 as well. Negative affinity works the same as positive affinity, except the you do anti-crits instead (do less damage instead of more). So if you have -15 affinity, each hit will have a 15% chance to do less damage than normal.
