Martial Artist Set Genshin Impact Farm. With only a 5% higher boost in exchange for 80 em and it is limited by conditions, martial artist works, but is beat out by wanderer’s trope. If you're able to get attack percent on both set pieces, then yes, that's better.
Keqing can theoretically maintain 100% uptime on the 4 set effect. Brave heart is a good set bonus for any dps characters. And even then the grind is ridiculously expensive compared to any other set in the game.
Genshin impact how to farm artifacts, artifact sets, artifact exp, rare artifacts, domains of blessing, and boss drops.
It is relatively easy to farm as it starts out as 3 star rarity. Gain a 15% geo dmg bonus: Even if you want to farm artifacts early, i'd wait for wl3 since level 30 gets you access to the 4* sets at least (martial artist, berserker, and exile are all pretty nice). All artifacts in the game belong to a set that further activates additional effects if pieces are worn together.
