Foreword
Quiry is a unit with poor eyesight, hence her disappointing combat performance. Her skills are very niché, and even then the values are too small to even make a noticeable impact. She seems to demonstrate a special predilection for defenders, increasing their attack and critical rate via Burst Skill. She also increases the HP of defenders, but it is currently not that useful, except in the case of 2B. Yet, it barely provides any boost, and bringing another B3 would be more justifiable. Attack reduction may come handy situationally for some content, both PvE and PvP. Finally, the last part of her kit is her overtime healing, which is a lot, but where would it be used?
Usage
Her main place will be in teams where B3 healer is preferred over B1 or B2. This frequently happens in Solo Raids, especially if you do not possess all the meta units. While her kit may be lackluster, if she allows you to survive for the whole 3 minutes, you will likely end up dealing more damage anyway.
Bossing
One potential usage for Quiry is in Modernia's team, where you run a 1-1-3 formation. Unless you run a healer in B1 or B2, a healer in B3 is often necessary for survival. In such cases, we usually resort to Helm, which not only provides healing every other rotation but also grants critical rate and ATK damage buff. With that said, Quiry can actually take over Helm's spot. The problem is that she does not have much to offer when it comes to offense.
PVP
She might usable in PvP as a copium unit. Her immense healing on Burst Skill is a great addition to stall teams, but stall teams have one major weakness — SAnis. If you consistently have the edge over someone (CP penalty), then with the right units, she might actually allow your team to survive a full 10-second SAnis' Burst Skill. However, other than that, you should deploy her with extreme caution. Since she is a B3 unit, it means you cannot use the skills of other B3, like Scarlet, SAnis, Alice, or 2B. This will result in lack of offensive firepower, and the only way you can win a battle is through surviving longer. Fortunately, her weaknesses should not be a major problem when attacking, as you can tweak teams according to the enemy's composition.
Team Compositions
Team #1
One variant of the PvP stall team you can adopt. Add Jackal if necessary. This team is focused on healing and ensuring that each of your units stays alive through the entire enemy's critical attacking window.
Team #2
The popular solo Modernia team with Miranda that usually utilizes Helm as the main healer. This team is occasionally seen in Solo Raids, especially with players who are not blessed with every single meta unit. Quiry can be used as an alternative to Helm, but she is still inferior. Note that Quiry works in any 1-1-3 teams, or even 1-2-2 or 2-1-2 teams, as long as you benefit from her heal. It does NOT have to be Modernia and follow this specific configuration.
Should You Pull
Should you pull? Not really.
Even if Anniversary weren't here, no. Her kit is just terrible. She is just a filler unit, so people can save gems. If you like her model and pose, then no one's stopping you from pulling at your own discretion.
