As the premier Anemo support unit for Anemo dps based teams, Faruzan combines both high Anemo damage buffing with Anemo resistance shredding to become a cornerstone of any team that wants to focus on Anemo damage. Though building her means primarily focusing on dealing with her high Energy Recharge Requirements.
For funneling particles to Faruzan:
For funneling particles to other characters:
Bear in mind that at [C6] the Charged shot portion of the rotation becomes no longer necessary since your Burst will start activating the Pressurized Collapses instead.
Regarding Weapon Choices:
Elegy for the End: Usually only a better option at higher constellation levels such as [C6] where her energy needs can be met without Favonius passive particles.
Sacrificial Bow: It's worth mentioning that the extra Pressurized Collapse from a second Skill wont give you any extra particles if it's within her 5.5 second particle generation cooldown.
Regarding Artifact Choices:
Sets
Noblesse Oblige (4): This is her best option in teams that either won't benefit significantly from (4) shred, or teams that already have another unit holding the aforementioned set.
Viridescent Venerer (4): This set should be used in teams which have a significant amount of Pyro/Hydro/Electro/Cryo damage. Note the resistance shred does not buff Anemo damage and the set wielder must Swirl the element(s) while on-field for the resistance shred.
Emblem of Severed Fate (4): This set will give Faruzan her best personal damage output, assuming the team is already running (4). Also if you're willing to invest more time farming substats it can potentially give you more Energy Recharge than running (2).
Golden Troupe (4): This set is better than (4) if Faruzan is [C6] because of the pressurized collapse damage.
Tenacity of the Millelith (4): This has similar usage cases to (4), except in that it requires Faruzan [C6] for improved uptime through extra Pressurized Collapse activations.
+20% ER set (2): Faruzan's Energy Recharge requirements pre-[C6] can be extremely high, so high that it can be difficult to build enough using a 4pc set bonus. As such, using (2) with whatever artifact combination will give you the most Energy Recharge is a reasonable option.
Main Stats
Anemo DMG: Due to Faruzan's high Energy Recharge requirements pre-C6, it is acceptable to disregard running an Anemo goblet in favor of a goblet which provides more Energy Recharge. A CRIT Rate circlet should still be taken to ensure Favonius procs.
Substats
CRIT Rate: Only assumes higher priority than CRIT DMG when using .
