Bounties are an essential part of the endgame in Rain and most restrict your gear. Here I will show and explain all the Builds I've used for them. For any bounty that doesn't restrict armor my general sets or even speedrun sets will be fine to use.
For weapon recommendations check the Weapon Collection. It has a GR section exactly for this purpose.
Here I'm going to show you two sets. The first will have no cuffs and follow the rules of not allowing Determination and Hiden Skills, perfect for Bronze Progression and some Free Bounties.
The Second Set will use cuffs and has Hiden Activated, perfect for the Bronze Urgent and Silver 1-8.
Note that both sets use SW.
It is not necessary to craft an optimized silver set. The classic Korinyi setup from progression should be enough especially if you complete the bounties in multiplayer, but anyway here's a somewhat optimized Korinyi set.
You could swap out the Diva Skill for SW and replace the Guild Food for more damage, but generally I recommend the below setup. Just keep in mind you need to get evasion from somewhere.
I have two sets prepared for gold progression although it is very possible to complete it with just the first or the previous silver set. Both builds need to get evasion from an external source. For the ZX set you should swap the cuff to Skill Slots Up PZ2 if you play a weapon that doesn't have Skill Slots Up as their zenith skill.
This bounty is weird since it has a very unique ruleset by allowing determination in a g-set. Not at all necessary to craft this set unless you want to hyper optimize a quest that doesn't give the best rewards.
A cuffless set can be useful in certain quests like multiplayer Legion or Gacha Narga. The set is very flexible in that regard and should work for all quests that don't allow any cuffs. You will need to get evasion from somewhere though.
