Rosaria

📄️ Rosaria

A sister of the church, though you wouldn't know it if it weren't for her attire. Known for her sharp, cold words and manner, she often works alone.

Basic Mechanics​

  • Frame data - Google Sheets - Kurt#5846 & Kolibri#7675
  • Rosaria's E is 1U Cryo on both hits and has no ICD
  • Rosaria's Q applies 1U Cryo on every damage tick with no ICD
  • Rosaria's CRIT bonus from her A1 is included in her A4 CRIT sharing
  • Rosaria's A1 CRIT bonus doesn't apply if you use her E while already behind an enemy

Passive: Night Walk​

Rosaria's passive doesn't work in the Serenitea Pot​

Finding:
Rosaria's passive does not work in serenitea pot (even after manual time switch to night time).

Evidence:
Overworld: Clearly faster - Imgur Serenitea Pot - Imgur

Significance:
Another evidence that the Serenitea Pot behaves similarly to Domains in game.

A1: Regina Probationum​

Rosaria's A1 Passive vs. Perpetual Mechanical Array & the Hypostases​

Finding:
Although Hypostases and Perpetual Mechanical Array don’t have obvious distinction between front and back in terms of visual, Rosaria can still activate her A1 Passive (12% CRIT Rate buff) by hitting them from certain angles.

Evidence:

  • Video
    In this clip I cast Rosaria E twice against Cryo Hypostasis in the same DPS window. The first E failed to activate A1 while the second E cast from opposite direction was able to activate it.

  • Video
    This clip contains two separate attempts of hitting Cryo Hypostasis after they performed the rolling attacks. In the first attempt, I hit them from “behind” and successfully activated the passive. In the second attempt I hit them from opposite direction and couldn’t get the buff.

  • Clips of Rosaria getting A1 buff against other bosses:
    Anemo Hypostasis - Video
    Electro Hypostasis - Video
    Geo Hypostasis - Video
    Pyro Hypostasis - Video
    Perpetual Mechanical Array - Video

Significance:
Rosaria can take advantage of her A1 Passive against the aforementioned bosses by the correct positioning. Which can be useful especially when these enemies appear in harder contents such as Spiral Abyss/Event Domains.

Rosaria Skill First Hit A1 Crit Buff​

Finding:
Rosaria's A1 passive does apply to the first hit of her skill

Evidence:
Google Docs sheet where I recorded all my Rosaria Es. 55 Rosaria Es were tested and all of them crit. If the A1 Crit Rate doesn't apply to her E then there would be a 0.0018% chance of this happening. I did a Chi Squared test with the expected values being if the A1 passive didn't apply and got a p-value of .0095 meaning its statistically significant
Videos of me doing the Rosaria Es:

YouTube

Significance:
Rosaria's skill snapshot before the first hit of her skill and since her CR applies to it she can do marginally more damage. This also doesn't match with the wording of her ascension which implies that it'll apply only after the first hit of the skill.

A4: Shadow Samaritan​

A4 Stacks with External Sources of CRIT​

By: The Immersive Fish#9373
Added: 2021-04-09 (v. 1.4)
Last tested: 2021-04-09 (v. 1.4)

Finding:
Rosaria's CRIT Rate sharing is influenced by other direct CRIT boosters.

This has been tested to work with Hu Tao's A1 and Geo MC's C1.

Evidence: YouTube

Diona : 29.9%
Rosaria A4 : + 8.8%

Diona w/ Rosaria A4 : 38.7%
Diona w/ Hu Tao A1 : 41.9%

While the Hu Tao boost is active, Ulting with Rosaria increases Diona's CR to 52.5% meaning that Rosaria's A4 is giving Diona 10.6% CR. This is an additional 1.8% CR when compared to the CRIT sharing uninfluenced by Hu Tao.

Significance:
This confirms that anything which influences a character's CRIT stats found in the details tab will influence the CRIT Sharing that Rosaria offers

Rosaria's C6 Debuff Refreshes on Hit​

By: Zendaju#3064
Added: 2021-04-15 (v. 1.4)
Last tested: 2021-04-15 (v. 1.4)

Finding:
Rosaria's C6 debuff is also triggered by the DoT on her Burst.

Evidence:
Video

Significance:
The description is misleading, and you can actually maintain 100% uptime on this Physical RES Shred.

Pale Flame on Rosaria​

By: Monado#9922

Last tested: 2021-05-01 (v. 1.5)
Discussion

Finding:
2 stacks of the Pale Flame 4-Piece set bonus cannot be achieved by 1 use of Rosaria's Skill despite the Skill being 2 hits (probably because the 2 hits are within 0.3s), and requires back to back usage to achieve the full 4-Piece effect.

Evidence:
YouTube
Also hitlag on Mitachurl shields wooden and geo still only grants you one stack per Skill use.

Significance:
This makes 4-Piece Pale Flame stacks somewhat difficult to maintain for carry Rosaria with, since her Skill CD is 6s and Pale Flame stacks last for 7s.
