Critical/Affinity

This guide was submitted by one of our guild members by the name of Newnar Zhou. Credit goes to him. He will be explaining about how affinity/critical works in this game.

1) Affinity Level or 会心等级 =/= critical chance or 会心率. Affinity level contributes to critical chance as a 2nd degree polynomial.

2) The passive skill Affinity Up or 达人 is misleading as it directly gives critical chance instead of increasing Affinity level. However it only increases critical chance linearly.

3) Because 2nd degree polynomially increments, this results in a massively increased critical chance as compared to a linear increment. Thus Affinity Up is much weaker and contributes much less to damage output as compared to Affinity level.

4) However, Affinity level is soft-capped at around 18, because the only things that give Affinity level are your weapons (can give up to +10) and your title (can give up to +8). But even a mere Affinity Level 14 is enough to get you 21.8% critical chance. Affinity Up on the other hand is capped at Affinity +5 (you need 30 skill points of 达人 to get that, mind you), where it gives you a much lower, flat +16% to critical chance.

5) Don't look down on +10 Affinity level weapons even if they have seemingly lower raw damage numbers! Because Affinity Level contributes massively more than Affinity Up, the amount of critical chance given by the +10 Affinity level is much much higher than even a skill like Affinity Up +4! This is compounded even further when you get the +8 Affinity Level title, your +10 Affinity level weapon can contribute a whopping 20% critical chance! This is important especially to those who use weapons with relatively fast attack speeds and attack instances.

6) Conclusion, prioritize getting your Affinity level up by getting those titles and using weapons that give affinity level. Affinity Up is a really weak skill and can be ignored. You should get Attack Up or other skills to boost your damage once Affinity level 18 is reached instead of trying to achieve even higher critical chance via Affinity Up because it is an exercise in futility.
