Question regarding affinity

So I recently decided to try and use the Hayabusa Feather in a set and see what I could do. Not very original or optimized but I am planning to farm Dreadking for armor and made this set to fight him.

Feather plus full Rathalos S for the remainder. I currently am running AUL and Crit Eye+3 for a balls to the wall attack set. For weapon I went with the Shagaru IG and built it for the speed Kinsect with an affinity plus 30 for white nectar.

My question is do all these affinities stack? Basically would I have +30 from CE3 +30 from White nectar +25 from IG for a 85% affinity?

Yes, they do stack. The overall increase in damage over time doesn't increase as dramatically for 10%-50% as it is for the 60%-100%. A critical hit is 25% increase in that unique hit. So if you have a 200 damage weapon, you would be hitting as if it was a 250 damage weapon.

For the best damage increase, it is better to increase many different attack up skills, instead of going stricktly critical.

hey-ho, idk how far ur up to but if u got silver los quest from hub u can use his armor with the crit earrings instead, wut makes critical so good in this ver of MH is critical boost.

also weakness exploiter is 50% increase of affinity also so u can easily get 100% hitting dreadking's face with silver los' set with bewst :D :D

If you're able too access the Fire Emblem DLC. You can utilize the Hayabusa and get Crit+2, Weakness Exploit and Crit Boost +1 free skill depending on charm.

This set would be better than Dreadking in terms of pure damage output, and isn't very hard to get.

I guess the most annoying part aside from the quest itself is doing Arena: Brachydios for the decorations for Critical Boost.

Good advice all, I am around HR 50 or so and have been working on Dread King armor. If anyone is on and wants to hunt some Silver Los/Hyper Los let me know.
