Vespera Boss Guide
Vespera is the 4th Threshold Boss, offering a challenge even to veteran players upon her release. Her vast array of positive and negative effects in play will require tight team compositions to beat her, and even then, her very high damage, coupled with the Max HP Seal, will make a 100% win rate difficult if your Defenses aren't high enough.
Still, Vespera comes with new Matrixes which will be a great way to diversify your strategies and improve your roster!
Vespera Overview
- Boss Name: Vespera.
- Element: Constant.
- Challenge Type: Threshold Boss.
- Difficulty Tiers: Normal → Hard → Nightmare → Hell → Inferno.
- Key Threats: High Damage, Debuffs, Max HP Seal, Turn Cycling.
- Recommended Strategy: Big damage per turn using high hit count Damage Dealers and out-of-turn Damage Dealers paired with multiple sources of spammable Offensive/Defensive effects.
- Disorder Units Disadvantage: On Hell and above, enemies deal bonus damage to Disorder affinity units. Additionally, Turn Meter- effects are reduced/nullified. On Inferno, all Debuffs are purified from Vespera when she gains an instant turn from her passive.
- Gear Sets: Check out which gear sets you can acquire, and what they do per boss here!
Skills Overview
Vespera's abilities and passive effects can catch you off guard if you're not prepared. Here's a detailed breakdown of her abilities and how to counter them.
Will Field (Passive)
Vespera and her Dreameyes are immune to all Turn Meter- effects, as well as all Control and [DoT] effects.
How to counter?
- SPD+/- and Turn Meter+: Focus on SPD manipulation and Turn Meter+ over Turn Meter-.
Vespera - Best Characters
In this section we will showcase the characters you can bring to deal with the boss - focusing more on ease of clearing the boss (rather than doing it super fast) and also to use as many SR characters as possible.
- Main DPS (Pick 2):
- There are very few ultra-dominant DPS options for this fight, since you ideally want each of your Animuses to be fulfilling 2+ roles during this battle. Even with the 200% increased damage, Disorder Animuses are among the highest damage dealers in the game, so they’re still highly advised.
Rosa - Incredible DPT (Damage Per Turn) and highest hit count. She is almost mandatory for smooth clears;
Xuan Li - Just like Rosa, Xuan Li boasts a stupidly high DPT, and her ability to Support and Debuff extremely reliably makes her the perfect choice for smooth and controlled fights;
Liliam - Still a ridiculous 2-turn Burst Nuker, Liliam is the perfect choice to pair with Rosa for fully optimized clears. Do not play her over Xuan Li if you cannot reliably clear in 2 turns; she is a speedrun unit for this fight.- Honorable mentions:
Raymerry 
Nathenn - Supports/Sustain hybrids (Pick 2):
- With Vespera's AoE Dispel and huge damage, it's important to have multiple sources of both Offensive and Defensive Supports. Each of them should preferably bring multiple vital effects to the table, limiting your options quite a bit. In this fight, Sustains must be able to offer Support/Debuff/Hit counts and cannot be Healers only.
Freya - The definition of all-purpose for this fight. High hit count, Buffs, Debuffs, Debuff prevention, Turn Meter+, small Healing; there isn't a single thing that a Codex Freya cannot do. Not used in Burst setups, as she offers limited Offensive potential compared to hyperbuffers;
Ninfoniel - Incredible Offensive Buff paired with one of the biggest Shields in the game, on top of having Immunity with the same button. Codex of Magic works wonders. Not used in Burst setups for the same reason as Freya, and she does not reduce the plume stacks;
Turandot - Offense, Defense, Turn Meter+ (S3) and high hit count (S2). Turandot is amazingly fast and can easily set your team up for success. She is used in place of Freya, although Freya provides more stability. Not used in speedruns for the same reason as Ninfoniel;
Areal - Extremely potent Buffs that can't be dispelled, and more Healing than you can use. The only downsides to Areal are her low hit count and Disorder Affinity;
Senyu - Extensively used in speedrun clears, Senyu has a high hit count, provides SPD+ and Immunity with one button press, all while running Revelation. Difficult to use in slower runs as she cannot compare to the other Supports in terms of stability;
Beyontin - Best Offensive Hyperbuffer, Beyontin offers massive damage buffs and CD reset to your main carry, which will be Liliam. Used only in speedruns.- Honorable mentions:

The Lumiwarden Diting ![Cachi [The Guard]](https://cdn.prydwen.gg/images/etheria-restart/characters/cachi-the-guard_icon.webp)
Cachi [The Guard] - Debuffers (Pick 1/2):
- Due to the strict requirements to beat Vespera and the difficulty of abusing Debuffs against her, very few 'pure Debuffers' find their place in most team comps. Still, some of them can be used either thanks to their overpowered kit or by adding them to optimized teams.
Plume - Still the queen of Debuffing, Plume easily fits in both stable and speedrun comps. Her Quills are undispellable and Codex of Magic provides her with high hit count and multiple crippling debuffs over 2 turns;
Dinah - Specifically picked in speedrun comps, Dinah provides 3 types of Offensive Debuffs and 4 hits with a single button press. Codex of Magic guarantees that both of your nuke turns are optimally set up.
Vespera Best Teams (Overall)
If you don't have some of the characters visible in the teams, you can replace them with another one that fulfills the same role (check the section above).
The teams for the section are targeted for the highest difficulty - Inferno - but obviously they will also work in the lower ones. Those aren't the only teams that work against the boss - only the ones we found to be optimal ones without overloading the team with Light/Dark characters.
