Mydei Tier List: The Ultimate Guide to Building Winning Teams in Honkai Star Rail
Introduction to Mydei: The Undying Lion Roars into Honkai Star Rail
The strategic landscape of Honkai Star Rail is set to evolve with the impending arrival of Mydei, a formidable new character scheduled for release on March 19, 2025, during the latter half of version 3.1. This highly anticipated addition to the playable roster will tread the Path of Destruction, a designation reserved for those who excel at dealing significant and often widespread damage, and will harness the power of the Imaginary element. This elemental typing places him in a unique position, making him only the second character to combine the might of the Imaginary element with the aggressive nature of the Destruction Path, following the precedent set by the powerful Imbibitor Lunae.
Unlike his Imaginary Destruction counterpart, who primarily focuses on enhancing his basic attacks, Mydei's combat style is deeply rooted in the manipulation of his own life force. His core Skill, aptly named "Deaths are Legion, Regrets are None," exemplifies this, functioning as a Blast ability that consumes a substantial portion of his current HP to unleash Imaginary damage upon both a primary target and any adjacent enemies. This inherent risk-reward dynamic is a defining characteristic of his gameplay, encouraging players to carefully manage his HP to maximize his damage output.
Further emphasizing this unique playstyle is Mydei's Talent, "Blood for Blood." This passive ability rewards him for enduring HP loss by granting him Charge points based on the percentage of HP he has lost. Upon reaching 100 Charge, Mydei enters the powerful "Vendetta" state, a transformation that restores a portion of his Max HP and grants him an immediate follow-up action.
While in the "Vendetta" state, Mydei undergoes a significant metamorphosis. His maximum HP is dramatically increased, bolstering his survivability and the scaling of his abilities. Additionally, his Basic ATK is enhanced, morphing into the formidable "Kingslayer Be King." Should he accumulate 150 Charge during this state, he gains an extra turn and automatically unleashes his devastating enhanced Skill, "Godslayer Be God." However, this immense power comes at a cost, as his DEF is reduced to zero in the "Vendetta" state, making him a glass cannon capable of dealing massive damage but also highly susceptible to enemy attacks.
To further complement his kit, Mydei's Ultimate, "Throne of Bones," serves a dual purpose. This Blast ability not only deals Imaginary damage to a primary target and adjacent enemies, while also taunting them, but it also restores a percentage of his Max HP and grants a significant amount of Talent Charge. This provides crucial sustain, allowing him to continue his HP-consuming attacks, and accelerates his progress towards entering the coveted "Vendetta" state.
As a character aligned with the Path of Destruction, Mydei's primary function within any team will undoubtedly be that of a Main DPS, tasked with inflicting substantial damage upon the enemy ranks. His capabilities extend to both single targets and multiple enemies, thanks to the AoE nature of his Skill and Ultimate. Furthermore, the inherent self-healing and HP-boosting mechanisms within his kit, particularly during the "Vendetta" state and through his Ultimate, suggest a degree of self-sufficiency that might, in certain team compositions, reduce the reliance on a dedicated healer, potentially freeing up a slot for a more offensive support or sub-DPS unit.
Understanding the Tier List Criteria: Forging Powerful Alliances with Mydei
To effectively evaluate which Honkai Star Rail characters will best complement Mydei's unique playstyle, it is crucial to establish clear criteria for synergy. Several key elements will determine how well a character pairs with the Undying Lion:
- HP and Damage Scaling: Given Mydei's intrinsic link to his HP, with his damage scaling significantly based on his Max HP, characters who can directly increase his HP pool or further amplify his damage based on this stat will demonstrate notable synergy.
- Skill Point Economy: Mydei's primary damage-dealing Skill consumes a considerable portion of his current HP, which may necessitate more frequent healing. Consequently, allies who are Skill Point (SP) positive or possess abilities that generate SP will be highly valuable in ensuring a smooth and sustainable combat rotation.
- Survivability: While Mydei possesses self-healing capabilities, his DEF being reduced to zero during his powerful "Vendetta" state leaves him particularly vulnerable to enemy attacks. Therefore, allies capable of providing shields, additional healing, or diverting enemy aggro away from him will be essential for maintaining his survivability and maximizing his damage-dealing potential. His Ultimate's taunt could also be strategically utilized in conjunction with allies who benefit from enemies targeting specific units.
- Turn Manipulation: The "Vendetta" state represents Mydei at his peak performance. Characters who can manipulate the turn order, either by Advancing Forward his actions or by delaying enemy actions, will play a crucial role in helping him enter and sustain this state for longer durations, thus amplifying his overall damage output.
- Damage Amplification: Finally, standard damage-boosting supports who can provide buffs such as increased DMG%, CRIT Rate, and CRIT DMG, or those who can inflict debuffs on enemies like DEF reduction or vulnerability, will synergize effectively with Mydei, further enhancing his already substantial damage potential.
When considering how Mydei might fit into various team structures, several common archetypes come to mind. His high damage potential and degree of self-sustain suggest he could excel in Hypercarry compositions, where he serves as the central damage dealer, supported by units dedicated to maximizing his offensive and defensive capabilities. He might also find a place in Dual DPS teams alongside another damage-focused character, although careful consideration of elemental coverage, SP economy, and any shared resource dependencies, such as HP consumption (as potentially seen with Castorice), will be necessary. While Mydei's Imaginary damage doesn't directly contribute to breaking all elemental weaknesses, his sheer damage output could prove beneficial in capitalizing on Weakness Break states inflicted by other members of a Break-focused team. Furthermore, supports who specifically enhance Break Effect could indirectly contribute to the team's overall damage.
In terms of the roles played by characters of different Paths, Harmony units will be indispensable for providing the necessary ATK, DMG, CRIT, and SPD buffs, as well as for manipulating turn order to optimize Mydei's performance. Nihility characters who specialize in reducing enemy DEF, applying vulnerabilities, or inflicting other damage-enhancing debuffs will significantly augment Mydei's damage output. Given his inherent HP consumption, reliable Abundance healers will be critical for maintaining his health and ensuring he can consistently utilize his abilities. Lastly, Preservation units who can provide shields will be invaluable in mitigating the damage Mydei takes, particularly during his vulnerable "Vendetta" state, while those with taunting capabilities can redirect enemy attacks away from him.
S Tier: Exceptional Synergies with Mydei - The Undisputed Best Partners
Sunday (Imaginary, Harmony)
Sunday's kit appears almost tailor-made to amplify Mydei's strengths. His Skill provides an immediate 100% Action Advance to a single ally, a boon for Mydei, potentially allowing him to enter his "Vendetta" state much more rapidly by taking additional turns to lose HP and accumulate Charge. The accompanying DMG boost of up to 30% directly enhances Mydei's damage output. Moreover, Sunday's Skill grants a significant 20% CRIT Rate buff for 3 turns, a crucial stat for maximizing Mydei's damage, especially considering his Trace that grants CRIT Rate based on excess HP. Sunday's Ultimate regenerates Energy for an ally and buffs their CRIT DMG based on his own CRIT DMG. This Energy regeneration can help Mydei use his Ultimate more frequently for healing and Charge, while the CRIT DMG buff significantly amplifies his damage in the "Vendetta" state. The added ability to cleanse one debuff from the target ally with his Skill provides vital protection for Mydei, preventing crowd control effects from disrupting his critical turns in the "Vendetta" state.
Tribbie (Quantum, Harmony)
Tribbie brings a unique and powerful form of support to a Mydei team. Her Skill grants all allies a substantial 24% All-Type RES PEN buff for 3 turns. This is an exceptional buff that directly increases the damage Mydei deals, regardless of enemy weaknesses. Her Ultimate deals AoE Quantum damage and creates a Zone that increases enemy DMG taken by 30%, further amplifying Mydei's damage against all affected enemies. Tribbie's Talent allows her to launch follow-up attacks that deal AoE Quantum damage after allies use their Ultimates, providing valuable supplementary damage. Interestingly, Tribbie's damage scales with her Max HP, creating a thematic synergy with Mydei, who also relies on HP for his damage.
RMC (Ice, Remembrance)
The Remembrance Trailblazer (RMC) offers a multifaceted support package for Mydei. Their Memosprite, Mem, can use its Skill to provide a 100% Action Advance to an ally and grant a True DMG buff for 3 turns. This Action Advance is invaluable for Mydei, potentially accelerating his entry into the "Vendetta" state. The True DMG buff provides a significant, unconditional damage increase. RMC's Ultimate summons Mem and grants it Charge, dealing AoE Ice damage. When Mem's Charge reaches 100%, it uses its Skill again, further enhancing action economy and True Damage. Mem's Talent also increases all allies' CRIT DMG based on RMC's CRIT DMG, directly benefiting Mydei. RMC's Technique delays all enemies by 50% upon entering battle, offering crucial setup time.
Sparkle (Quantum, Harmony)
Sparkle's kit is designed to empower a primary damage dealer like Mydei. Her Skill increases a single ally's CRIT DMG and Advances Forward their action by 50%. The CRIT DMG buff is essential for maximizing Mydei's damage, especially in "Vendetta," and the Action Advance aids in faster Charge accumulation. Her Ultimate recovers 4 Skill Points for the team and grants "Cipher," enhancing her Talent's DMG boost. This Skill Point recovery is vital for teams with HP-consuming DPS like Mydei. Sparkle's Talent provides a team-wide DMG boost whenever an ally consumes a Skill Point, further amplifying Mydei's damage.
Luocha (Imaginary, Abundance)
Luocha offers exceptional healing throughput, crucial for sustaining Mydei's HP consumption. His Skill provides immediate healing, and his Talent deploys a Field that heals attacking allies, offering consistent passive recovery. Luocha also has an AoE dispel on his Ultimate, removing enemy buffs. Importantly, Luocha is very SP-friendly, ensuring Mydei has enough Skill Points for his abilities.
Gallagher (Fire, Abundance)
Gallagher provides reliable healing to offset Mydei's HP loss. His Ultimate inflicts the "Besotted" debuff, increasing enemy Break DMG taken, and heals attackers of "Besotted" enemies. His healing scales with Break Effect. Gallagher's enhanced Basic ATK reduces enemy ATK. He is also SP-positive.
