Comparison Between Mika & Diona
Depends On The Team Comp
In order to find out the better Cryo support & healer between Mika & Diona, you should consider the team comp first as this will determine the support needed by the main DPS.
Both Can Be Included In A Physical Team Comp
| Sample Lineup with Mika & Diona | |||
|---|---|---|---|
| Razor Physical DPS | Yun Jin Normal ATK Buffer | Mika Physical DMG Buffer | Diona Shielder & Healer |
Since Mika's Cryo application is bad, you can put them both in a team with an Electro character that inflicts Physical DMG such as Razor.
Physical Team Comp With Mika
| Hypercarry Physical DPS | |||
|---|---|---|---|
| Eula Physical DPS | Raiden Shogun Electro Support | Zhongli Shielder | Mika Buffer & Healer |
Mika can increase the damage output & ATK SPD of Eula. Mika's ATK SPD buff stacks with the ATK SPD bonus from Eula's signature weapon, Song of Broken Pines.
Elemental Reaction Team Comp With Diona
| Freeze Team | |||
|---|---|---|---|
| Ayaka Main DPS | Xingqiu Hydro Support | Kazuha Support Amplifier & Crowd Control | Diona Shielder & Healer |
Diona can shield, heal, produce Cryo particles for Ayaka, and apply Cryo to the enemy that can easily be swirled by Kazuha. With C6, the EM bonus is beneficial for Kazuha.
Who Is Better Cryo Support & Healer?
Cryo Vision
| Cryo Vision Placement | |
|---|---|
 Mika's right hand |  Diona's shaker |
Mika & Diona can apply Cryo to the enemy. Even if Mika uses a polearm, aim shot can still be used. This aim shot is the same as Diona's but Mika can only do this thru Skill.
HP-Scaling Characters
Aside from Cryo vision, another similarity is that they both scale with HP. With higher HP, the support that Mika & Diona can provide becomes better. But which one is better between two?
Mika As Cryo Support & Healer
Tailored For Physical DPS
Mika is tailored to support Physical DPS such as Eula. Apart from healing, Mika has buffs that can improve the damage output of the Physical DPS in the team.
Aim Shot For ATK SPD & Physical DMG Bonus
Attacking an enemy with an aim shot thru Mika's Skill increases the active character's ATK SPD & Physical DMG temporarily. The buff lasts for 12s and has a cooldown of 15s so it has 3s downtime. Also, the active character gains 60% Physical CRIT DMG when C6 has been unlocked.
Buff With Heal From Burst
Mika's Burst instantly heals the team and the active character can restore more HP to oneself when attacking while the buff is active. The buff lasts for 15s and has a cooldown of 18s so managing to fill up the required energy makes it 3s downtime.
Stacks For Physical DMG Bonus
You can gain stacks that increase the Physical DMG: 1 stack can increase the Physical DMG of the active character by 10%.
How To Gain Max Stacks?
Initially, the max stack is up to 4 but it is increased by 1 when C6 has been unlocked. To gain the max stacks from Mika, cast his Skill by holding and hitting at least 4-5 enemies or simultaneously activate buffs from Skill & Burst. While the buffs are active, the active character gains 1 stack when scoring CRIT hit.
Diona As Cryo Support & Healer
Can Fit In Different Team Comps
Diona is flexible support that can fit in most team comps, especially team comps that involves elemental reactions. She has a shield & heal that can keep the active character safe.
Diona Best Build & WeaponActive Buffs While Shielded
Aside from being shielded from incoming damage, one of Diona's passive, Cat's Tail Secret Menu, gives the active character active buffs while shielded: the movement SPD is increased by 10% while stamina consumption is decreased by 10%. The buffs are useful for both exploration & combat.
Skill Can Be Used Twice With Sacrificial Bow
The passive effect of Sacrificial Bow has a chance to reset Diona's Skill enabling her to cast Skill and produce a shield twice which is great for prolonging the shield.
AoE With Heal Per Second From Burst
Using Diona's Burst lets her throw her signature mix that summons a healing AoE for 12s. In order to restore HP, the active character must be inside the range. Only 1 character can be healed at a time so if all of your characters need healing, you should switch them out one by one.
Burst AoE Buff & Debuff
One of Diona's passive, Drunkards' Farce, has a debuff that decreases the ATK of enemies when inside the AoE by 10% for 15s which is great for prolonging her shield. In addition, unlocking her C6 lets the active character inside the AoE gain 200 EM bonus if the active character's health is above 50%.
Mika Vs Diona Tips
Mika As ATK SPD Buffer
With ATK SPD buff, Mika can hasten the combat execution of characters that utilize normal attacks such as Yoimiya, Wanderer, & Ayato. Mika's ATK SPD buff can stack with other ATK SPD from different sources like Yun Jin's C6 & Jean's C2.
If Mika & Diona Are In A Single Team
Diona Is A Great Battery
When Mika & Diona are included in a single team, you can focus on the full HP build for Mika since Diona can already generate Cryo particles, especially with Sacrificial Bow.
Artifact With HP Main Stat Plus Black Tassel
Mika's buff scales with his max HP so focusing on HP would make his buff even better. Use artifacts with HP main stats plus Black Tassel to significantly increase Mika's max HP.
Use Different Artifact Set
Between Mika & Diona, you can only choose one user for Noblesse Oblige x4 because the ATK buff does not stack. Instead, use artifacts that can increase HP & healing bonus such as Tenacity of the Millelith, Maiden Beloved, & Ocean-Hued Clam.
Prioritize Mika For Noblesse Oblige
Since you can optimize the ▲stacks when both of Mika's buffs are active, it is better to equip Mika with Noblesse Oblige over Diona. You can equip Diona with mentioned artifacts above which are beneficial for Diona's shield & heal.
Favonius Lance For Extra Energy Particles
If you want to produce more particles, you can opt for Favonius Lance instead of Black Tassel for Mika.
