Non-charged Aimed Shots share Elemental application ICD with Charged Aimed Shots, despite not having an Element themselves
Added: 2020-11-19 (v. 1.1)
Last tested: 2020-11-19 (v. 1.1)
For Diona, who's charged shot ICD is higher than the time it takes to fire a second charged shot, this prevents Elemental reactions or aura application from occurring on a fully charged shot if you fire a normal aimed shot by accident before it, if the ICD was not active yet.
Diona Dash Aim Cancel

Last tested: 2021-10-17 (v. 2.2) Discussion
Diona can cancel her dash early with Aim Toggle (R on PC, L2 on controller).
With C4: Imgur
Diona can dash aim cancel after doing one of the following actions after switching in:
- Enter Aim Mode
- Normal or Charged Attack (can cancel it before the attack comes out)
- Hold Skill (Tap Skill does not work)
- Plunge Attack
Very fast way to shoot CAs with Diona while still retaining the ability to aim (since ARCC cannot be aimed)
Aimed Shot Damage Dropoff
Added: 2022-10-23 (v. 3.1)
Last tested: 2022-10-23 (v. 3.1)
Aimed Shot damage and GU dropoff is based on the amount of time that the arrow travels in the air.
For the first 0.7s, there is no damage dropoff.
After 0.7s, every 0.05s:
- The damage will reduce by 10%, for a maximum of a 90% reduction.
- The Gauge Units will reduce by 10%, for a maximum of a 90% reduction.
- Imgur: arrow travels for 55 frames (13 frames of dropoff), DMG and GU reduction should be 40%; DMG was reduced from 2006 to 1204, Cryo aura lasted for 8.5s which lines up with the formula (
- Imgur: arrow travels for 50 frames (8 frames of dropoff), DMG and GU reduction is expected to be 20%; DMG reduced from 2319 to 1855, aura lasted for exactly 9 seconds (
- Imgur: 63 frames travel time (21 frames of dropoff), DMG reduction is as expected 70% (2350 -> 705).
- Imgur: arrow travels for 96 frames (54 frames of dropoff), DMG was reduced from 2350 to 235, aura lasted for 7s 19 frames which is roughly in line with 0.1GU's duration (
2.5+0.1+7=7.25s), proof that DMG dropoff caps at 90%.

Diona Elemental Skill ICD analysis
Added: 2020-11-18 (v. 1.1)
Last tested: 2020-11-18 (v. 1.1)
The first 2 (tap) and last 3 (hold) projectiles of Diona's Elemental Skill have separate Element application cooldowns.
After applying a strong fire aura (Bennett E), I applied a Cryo trigger from Diona's E.
Tested waiting between Bennett's E and Diona's E to downgrade the fire Element strength.
Bennett E + (no wait) + Diona E (tap) = 1 Melt reaction + weak Pyro aura remaining on enemy.
Bennett E + (no wait) + Diona E (hold) = 2 Melt reactions + no Element remaining on the enemy.
Bennett E + (wait 5+ seconds) + Diona E (tap) = 1 Melt reaction + no Element remaining on the enemy.
Bennett E + (wait 5+ seconds) + Diona E (hold) = 1 Melt reaction + Cryo aura remaining on the enemy.
Bug: Diona's shield is 2U under specific circumstances that are guaranteed on swap
By: Monochrom9#8058, Help Me with Honours#1678, Zeitraffer#1074
Diona's shield was most likely meant to be 1U like every other self-aura in the game. miHoYo may have implemented a failsafe for Diona's e missing that forms a shield anyway, and this redundant shield ALSO applies 1U and can appear even if her e does connect functionally making it a 2U application and the largest self aura in the game. The fact that it is strangely particular in when and how it applies the 2U instead of 1U makes it more likely that the scenario where you get 1U of Cryo instead is intended instead of the other way around.
Hopefully, miHoYo just makes her shield more consistent when it comes to cleansing herself in a future patch, but the workaround from the below video can be used to cleanse the team with 1 less swap in the meantime. My speculation as to WHY this happens has to do with some observations and ideas about how shields work in general.
When a character swaps, the whole character gets entirely removed from play and then replaced with the new one and it SEEMS that it keeps the same shield. But if we make a certain assumption that shields function like buffs, then some things start to make sense. For example, because shield effectiveness is a statistic, moving the same exact shield across characters wouldn't be correct as we know that shields have different values across characters with different shield effectiveness.
To solve this they save the base shield value, remaining shield, and duration and apply these characteristics to the new shield upon character swap. The old shield then ceases to exist under normal circumstances and a new shield is immediately created using the saved characteristics on the new character adjusted for shield efficiency. Since Diona's shield ALSO applies Cryo to the character they would also need to apply Cryo to the character and this is where things might be going wrong in between shields, the method that they are using to apply the Cryo may linger for too long across swaps and apply to the new unit on top of the normal shield that they generate.
I'm not 100% certain it works this way, but Noelle had a similar bug that leads me to believe shields work like this. In the Noelle video below, under the above theory, the shield is just breaking instead of ceasing to exist on swap like it is supposed to, and the timing for the glitch being identical to the current subject raises my eyebrows.
Unfortunately, this comparison has some issues such as Diona shield not caring about ping and the above theory failing to explain how the first shield could apply 2U. I have no idea at this time how to construct an experiment that would prove definitively that this is how shields actually work and is honestly outside the scope of this entry, but these two bugs are suspicious in their shared timings and could be worth scrutinizing.
Note: Diona cleansing Pyro aura is inconsistent and can be 1U, 1.5U or 2U depending on the aura also it does not apply 2U to Diona herself until the second swap.

Last tested: 2021-10-15 (v. 2.2)
Finding: Diona's Skill Icy Paws do not form a shield if all Icy Paws despawn before hitting something.
1 Icy Paw hit generates 2.4s shield: YouTube
0 Icy Paws hit generate no shield: YouTube
Icy Paws revolve around a non-activated Ruin Guard until they eventually despawn and no shield is formed: YouTube
At least 1 Icy Paw must hit something for a shield to form. Situations where Icy Paws might despawn before hitting something include:
- Standing on a cliff with no ground below
- Targeting an enemy without ever hitting it, including non-activated Ruin Guards

Diona's paws appear behind Diona and then move forward during hold E. In the following clip the paws appear behind Diona inside the wall and explode before being able to travel forwards. Since no enemies got hit, no DMG got dealt and no Particles were generated, however she still gets her shield up.
Don't fire Diona's paws when there is a wall behind you.

Diona's Elemental Burst has a finite vertical range of healing, in contrast to known fields that have infinite vertical range (e.g., Bennett).
Diona's Burst not healing compared to Bennett's Burst that will heal (in coop): YouTube
Diona's Burst does not heal when the Burst AoE is far below the character: YouTube
Diona's Burst does not heal when Burst AoE is above the character, unlike Bennett's Burst: YouTube
Diona's Burst does heal above its visual AoE within a vertical range slightly shorter than the height of the Shrines of Depths: YouTube
Diona's Burst does heal below its visual AoE within a small vertical range: YouTube
Diona's Burst may not heal Xiao in his Burst because his jumping height is higher than Diona's Burst vertical range: Imgur
Diona's Burst healing has a limited range in contrast to all other known healing fields that have infinite vertical range.
This has implications against Xiao (or for Xiao with Staff of Homa) because the height limit is lower than Xiao's jump height.

Diona C1 Range and Q Duration

Last tested: 2022-05-12 (v. 2.6)
While doing tests for another ticket, I accidentally found out that Diona's C1 seems to have no range limit, I went to test it out and found out that it seemingly indeed have infinite range when on the same map, when teleporting to a different map such as Enkanomiya or Teapot, however, the C1 fails to proc, as can be seen in the evidence 2-5, where Diona does not gain the Energy from C1.
Diona Q Duration:
We can also see that Diona's Q, Signature Mix, field duration starts when the paws disappear from the field, which in my tests happen at around ~17.5s timer on the Burst cooldown, this checks out due to the field having a 12s duration and Diona gaining the 15 Energy from her C1 at around ~5.5s timer on the Burst cooldown, 17.5 - 5.5 = 12.

- 49/50 R3 4-5 enemies hit in Abyss (theoretical between 97.44% and 98/976%) YouTube
To find out why diona is not proccing Sacrificial Bow correctly, both Sac and Fav Bow were tested on Diona to ensure that it was simply not Diona's Hold E being weird in general, Sac weapons were tested on hitting multiple enemies to see if it triggered correctly, Sac Sword was tested on hitting one enemy multiple times with the same Skill (EMC E) to see if it triggered correctly, and Sac Bow specifically was tested on hitting multiple enemies to see if it triggered correctly.
The results of the testing shows that everything works pretty much as expected except Diona's Hold E on Sac Bow. While we currently do not know the source of this anomaly, the scope of this entry is to record and document its existence. Since Diona as a battery sometimes uses Sac Bow, knowing she doesn't proc it as well as math dictates means Energy calculations with Sac Bow should change to reflect that she doesn't follow standard math.
