Overview
AS Val’s new Skill2 grants her surehit for 3 seconds after gaining a Damage buff. This means she has surehit for the first 3 seconds of her Skill1 on her own, with other sources (such as buffs or Fervor talent from Fairies) granting her higher uptime. While her Skill1’s uptime is still not amazing, this is pretty much a non-issue as Ribeyrolles is a staple for most ARs and their uptimes match perfectly. With this, AS Val can generally ignore equipping a PEQ at Night and instead use a VFL and Focus Chip.
As AS Val has surehit, her benefit greatly depends on what enemies you are facing at Night. With many low to medium Evasion enemies, just about any strong AR with a PEQ will likely do the job just fine, but when you do want that surehit, AS Val’s performance is quite good.
With all that said, AS Val is still a front-targeting AR; there are many other strong surehit options, and other strong ARs will perform just fine with PEQs in most fights. As such, she is not a high priority.
