Frequently Asked Questions
Is arknights endfield si better as a main DPS or support?
Si excels primarily as a sub-DPS and support operator. While her personal damage is remarkably high—especially with optimal gear—her true strength lies in her ultimate's elemental amp and cooldown reduction capabilities that benefit the entire team.
How does Si's Proxy's Patronage talent work?
This talent reduces the combo skill cooldown of the operator stationed in the first team slot immediately after Si casts her ultimate, enabling much faster and more fluid damage rotations.
Which gear set should I farm for Si?
The Type 50 Yinglung set paired with a Redeemer Seal (for Ultimate Efficiency) or LYNX Slab (for raw damage) is universally recommended for endgame builds.
