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.
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.
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.

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.
A4: Shadow Samaritan
A4 Stacks with External Sources of CRIT
By: The Immersive Fish#9373
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.
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 characters crit stats found in the details tab will influence the Crit Sharing which Rosaria offers
C6: Divine Retribution
Rosaria's C6 Debuff Refreshes on Hit
Finding: Rosaria's C6 debuff is also triggered by the DoT on her burst.
Finding: 2 stacks of the Pale Flame 4 piece set effect 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.
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.
