"What is the best farmer class?" Other: Neon Ninja, Me: Knight without class gem. Why? It is easy-to-unlock Starter Class that still useful in endgame. It's just that Trovians underestimate him, touching class gem, and then said X class move faster and therefore Knight is terrible. It isn't when one realized "2 Hit registration" Dashing attack.
This is not a "random" build. Fae is one of the best U10 farmer, can match Dino Tamer due to quality Skill 1 and boosted basic attack. However, it is an Energy-heavy class. Fae would be average if you play her as "another farming class".
this is a build of my 34.2k LL i use for grinding u9 stellar gems and u10 cosmic gems. if your ganna run delves with this. (not recommended) max your path painter so you can be a runner. subclass knight for more vials not so much for mount movement speed (unless you have ganda ;)
(WORK-IN-PROGRESS. i'm lazy so i'll do this when i have free time. this is just for those who main knight (nice choice :D ), and want a little guidance from someone who's been maining the Knight since 2014.
This is my Ice Sage build for Delves. It is not great at farming, as it has very low Movement Speed. This is a raw damage build, for highest DPS possible, while still being able to survive deep Delves.
This build is a decent all-purpose Ice Sage DPS build. If you do not need extra potions for a long fight or faster mounted movement speed, you can use a different subclass depending on what your needs are.
