Mona's primary goal is to use her Elemental Burst, Stellaris Phantasm, to create massive elemental reaction damage. She can also use her standard Elemental Skill, Mirror Reflection of Doom, to create space on the battlefield by summoning an Illusion that continuously taunts enemies and deals Hydro damage whether she is on or off the field. However, Mirror Reflection of Doom only last 5 seconds, so it can be difficult to complete a full team rotation before it ends.

Mona's weapon of choice, Thrilling Tales of Dragon Slayers, can create some great reactions when you bring a Main DPS onto the field, giving them an ATK buff from her weapon. However, choosing this weapon does take a lot away from Mona's DPS, leaving her as pure support. Her second choice, Prototype Amber, is also great for her as support role allowing a team-wide heal whenever she uses her Burst ability. Lastly, she can equip Blackcliff Agate, which offers Mona a much more offense stats to try and kill the smaller enemies to trigger the weapon's team-wide ATK buff. These weapon choices are designed to focus on her support capabilities and not her personal damage.

Mona's artifacts are quite important for her team, as they focus on Energy Recharge and buffing your teammates ATK. Our Energy Recharge needs are quite high for Mona and we need to aim for over 220% Energy Recharge for quick rotations on the battlefield while you chain elemental reactions together. We also stack critical stats on Mona to help with the DPS of our reactions when her Hydro is combined with other elements. While Mona is not focused on DPS in this build, she can still provide the opportunity for substantial burst damage.

Mona supports a Main DPS by using her Elemental Burst, Stellaris Phantasm, to apply her Omen Damage Buff to whoever breaks the Illusionary Bubble she creates. This offers you a very technical method of applying this damage buff to exactly which character you want to use it on. This Elemental Burst skill also applies Hydro on all enemies nearby, which is used to create huge bursts of damage by combining elements with your chosen DPS. Mona's Burst ability has three main components to it, they are as follows.

1. Applies Hydro to enemies.
2. Creates the Illusionary Bubble.
3. Grants the Omen buff to whichever character breaks the Illusionary Bubble.

Understanding these three components will help you setup and create huge Elemental Reactions to take down bosses with ease. The buff does have a timer on it, so be aware of what order you are doing your rotations in. You want your Main DPS to activate the buff, then continue to play on-field with your them to take advantage of the Omen's buff.

Support Mona sets the stage for some crazy elemental reactions and is typically kept off-field until the conditions are perfect for her step out and use her Stellaris Phantasm. Mona also has her Elemental Skill, Mirror Reflection of Doom, which should be cycled into your rotations while you build up her Burst ability to augment your team's damage.

This team is all about dropping Mona's Stellaris Phantasm for Bennett to charge in and break the Illusionary Bubble with his Fantastic Voyage. Right before Mona deploys her Elemental Burst, we want to have Kazuha and Sucrose use their Burst abilities to add their own buffs to Bennett. The rest of the play time is used to apply Elemental Reactions and keep Bennett on the field using his claymore attacks. This build is typically made for nuking world bosses and does not perform the best without properly setting up your skills on the battlefield. However, it has to be included on this build list as it showcases some truly powerful one-shot mechanics against world bosses.

This Freeze build focuses on a double damage buff for Ganyu, using Kujou, Sara, and Mona to trigger some massive Freeze damage once you destroy Mona's Illusionary Bubble with Ganyu. The rotations are easy to perform and keep track of, keeping Ganyu on the field while Mona's Mirror Reflection of Doom helps manage the enemies while you stay ranged with Ganyu. Diona also helps with additional sources of freezing, and her shield/healing to keep the team going while you build up Mona's Elemental Burst, Stellaris Phantasm, to start the cycle all over again. Overall, this combination of damage, freezing and shielding/healing will help you survive against most of the game's content.

This Double Hydro build once again focuses on using Supports and Buffers to push Ayato's damage as high as possible. Mona's role here is the same as with previous builds, using her Stellaris Phantasm to apply her Omen buff to Ayato's ultra fast sword attacks with his Kamisato Art: Kyouka. We also use Kazuha to pull enemies together for this devastating combination from our two Hydro users and offer his damage buff to Ayato as well. Lastly, we have Yun Jin whose Elemental Burst, Cliffbreaker's Banner, adds bonus damage based on her DEF (build her with that in mind) to any teammate's Normal Attacks. Despite Ayato using either of his abilities, they are still consider Normal Attacks and will take full advantage of all of these buffs. Lastly, Yun Jin can use her Elemental Skill, Opening Flourish, as a shield to absorb any boss attacks or protect you when you cannot escape from damage — rounding out the build with some good survivability.
