Nihility
Lightning5★ “Lone voyagers in the cosmos are driven by two desires: to tread in the trails of the past and to forge their own way. But under THEIR scrutiny… most end up adhering to the former.”
Acheron is an Ultimate-focused DPS who does not use Energy like everyone else. Instead she builds up Slashed Dream points. Her Ultimate ignores Weakness Types, so she handles every kind of enemy and fits almost any stage. If you are missing a main DPS you can rely on for a long time, she is a very good use of your pulls.
She suits players who already own (or plan to pull) more Nihility characters, because she is at her strongest next to two other Nihility units. If your roster is all Harmony characters and you have no Nihility units yet, think it over first.
Even though she walks the Path of Nihility, Acheron builds like a normal crit DPS. Focus on CRIT Rate, CRIT DMG and ATK and you are set.

ATK% and SPD boots both work. SPD lets Acheron act more often, so she collects Slashed Dream faster, but if Sparkle is on the team just take ATK%. For the sphere, ATK% is slightly better than Lightning DMG Boost because she already gets plenty of DMG bonuses from her Traces.
Try to keep a ratio of about 1% CRIT Rate to 2% CRIT DMG.
Her Ultimate deals most of her damage, so level it first. Her Talent sets how much All-Type RES she strips from enemies during the Ultimate. Leave Basic ATK for last, since you will be using her Skill almost all fight long.
The Abyss is the most important Trace: with 2 other Nihility characters on the team, Acheron's DMG goes up to 160% of the original. All three are worth unlocking early.
E1 gives 18% CRIT Rate when hitting debuffed enemies, which lets you shift your substats toward CRIT DMG. E2 means only 1 other Nihility character is needed for The Abyss to reach its full effect, and she also gains 1 point of Slashed Dream at the start of each of her turns. From E2 you can put Sparkle, Sunday or Bronya in the second Nihility slot.
Mortenax Blade is currently Acheron's best Nihility teammate: he applies debuffs constantly, lowers enemy DEF and raises the whole team's Ultimate DMG. Cipher makes every enemy take more DMG, and Jiaoqiu is a very strong replacement for her. With her signature Light Cone, Hyacine lets Little Ica apply a debuff every turn, so she heals the team and helps Acheron collect Slashed Dream at the same time.
This team needs no limited characters other than Acheron. Pela and Guinaifen are both Nihility, so The Abyss still reaches its full effect. Pela lowers DEF across the field, and Guinaifen keeps applying Burn so Acheron keeps gaining Slashed Dream. Gallagher heals and also applies two kinds of debuffs, one from his Ultimate and one from his Enhanced Basic ATK.
At E2, one Nihility teammate is enough to max out The Abyss, so the other slot can go to a Harmony character who advances her turns. Acheron acts more often and builds her own Slashed Dream much faster.
Her strongest Nihility teammate right now. He applies debuffs even during enemy turns, raises Ultimate DMG and lowers enemy DEF.
Makes every enemy take more DMG while she is on the field. With a Light Cone that applies debuffs, her Follow-up ATK adds extra debuffs that feed Acheron.
One of the best Slashed Dream generators, since he applies debuffs during enemy actions. He also makes enemies take a lot more Ultimate DMG.
Implants a Lightning Weakness on enemies and lowers DEF across the field with her Ultimate.
Lowers DEF, Slows enemies and delays their turns. Do not pair him with Jiaoqiu, though, because Jiaoqiu needs enemies to act before he can apply his debuffs.
An easy-to-get 4-star who lowers DEF across the field with her Ultimate and gets her Ultimate back very quickly.
Her steady stream of Burn helps Acheron collect Slashed Dream at a regular pace.
With Long May Rainbows Adorn the Sky, Little Ica applies a debuff every turn, so she heals and feeds Slashed Dream at the same time.
A 4-star healer who applies two kinds of debuffs, a good fit for budget teams.
Shields the team and boosts Acheron's ATK. Give him Trend of the Universal Market for a chance to apply debuffs during enemy actions.
Acheron does not need Energy. She needs 9 points of Slashed Dream, which come from two places: her Skill gives 1 point each time (2 with her signature Light Cone), and whenever any unit uses an ability that inflicts a debuff on an enemy, she gains 1 point. So the more debuffs your team spreads, the more often Acheron can use her Ultimate.
Whenever an ability debuffs an enemy, that enemy also gets 1 stack of Crimson Knot. If several enemies are debuffed at once, the stack goes to the enemy that already has the most. When you use her Ultimate, you pick the target for each of the first three Rainblade slashes. Each one removes up to 3 Crimson Knot stacks from its target, and if it removes any, it also deals extra DMG to all enemies, more for every stack removed. The last hit, Stygian Resurge, strikes every enemy. Aim at the boss or whichever enemy has the most Crimson Knots for the best payoff.
During her Ultimate, Acheron reduces enemy Toughness regardless of Weakness Types and lowers their All-Type RES. That means you do not have to swap teams based on enemy weaknesses the way you would with many other DPS characters.
Her Technique instantly defeats normal enemies in the overworld, and if you miss, no Technique Point is used. Against Elite enemies and bosses, it deals Lightning DMG at the start of the fight and gives her Quadrivalent Ascendance, which hands back 1 point of Slashed Dream after she uses her Ultimate. On top of that, the Red Oni Trace gives her 5 points of Slashed Dream as soon as the battle starts, so her first Ultimate usually comes very early.
Deals Lightning DMG equal to 140% of Acheron’s ATK to one designated enemy target.
Gains 1 point(s) of “Slashed Dream.” Inflicts 1 stack(s) of “Crimson Knot” on one designated enemy target, dealing Lightning DMG equal to 200% of Acheron’s ATK to this target, as well as Lightning DMG equal to 75% of Acheron’s ATK to adjacent targets.

“Rainblade”: Deals Lightning DMG equal to 28.8% of Acheron’s ATK to one designated enemy target and removes up to 3 stacks of “Crimson Knot” from the target. When “Crimson Knot” is removed, immediately deals Lightning DMG equal to 18.0% of Acheron’s ATK to all enemies. For every stack of “Crimson Knot” removed, this DMG Multiplier is additionally increased, up to a maximum of 72.0%.
“Stygian Resurge”: Deals Lightning DMG equal to 144% of Acheron’s ATK to all enemies and remove all “Crimson Knots.”
“Crimson Knot” cannot be applied to enemies during the Ultimate.
When Slashed Dream reaches 9 point(s), the Ultimate can be activated. During the Ultimate, reduces enemies’ Toughness regardless of Weakness Types and reduces all enemies’ All-Type RES by 25%, lasting until the end of the Ultimate.
When any unit inflicts debuffs on an enemy target while using their ability, Acheron gains 1 point of Slashed Dream and inflicts 1 stack of Crimson Knot on a target. If debuffs are inflicted on multiple targets, then the 1 stack of Crimson Knot will be inflicted on the enemy target with the most Crimson Knot stacks. This effect can only trigger once for every ability use.
After an enemy target exits the field or gets defeated by any unit while Acheron is on the field, their Crimson Knot stacks will be transferred to the enemy target with the most Crimson Knot stacks on the whole field.

Quadrivalent Ascendance: After using the Ultimate, Acheron gains 1 point(s) of Slashed Dream and inflicts 1 stack(s) of Crimson Knot on a single random enemy.
If attacking a normal enemy, immediately defeats them without entering combat. When not hitting enemies, no Technique Points are consumed.
When dealing DMG to debuffed enemies, increases CRIT Rate by 18%.

Increases the All-Type RES PEN for the Ultimate DMG dealt by Acheron by 20%. The DMG dealt by Basic ATK and Skill will also be considered as Ultimate DMG and can Reduce enemy Toughness regardless of Weakness Types. When breaking Weaknesses, triggers the Lightning Weakness Break effect.
Acheron is a damage dealer who builds up the Charge she needs for her Ultimate by inflicting debuffs on enemies. While her Ultimate is active, she ignores enemy Weakness Types and Toughness reduction rules and lowers the elemental RES of all enemies. During exploration, Acheron’s Technique can also instantly defeat certain enemies.
