Acheron Best Teams

Acheron F2P Team

For a F2P team, you can use Acheron with Mortenax Blade and Welt. Both of them apply enough debuffs to consistently stack up Acheron's Ultimate. Mortenax Blade also boosts the Ultimate DMG of the whole team, along with a general DMG amp. Welt brings DEF shred and delays the enemy's turns. Permansor Terrae acts as the sustain character of the team, providing ATK to Acheron and shields for the team.

Beginner Team

For beginners who don't have any limited 4-Star or 5-Star characters yet, Asta and the Fire Trailblazer can debuff the enemy through Burn and Taunt respectively. The Fire Trailblazer can equip the Trend of the Universal Market to apply Burn on enemies. Since Acheron's kit becomes stronger when Nihility units are in the party, we recommend replacing your Supports as soon as you get debuffers.

Acheron Nihility Team

Acheron's best team at Eidolon 0 and 1 consists of two other Nihility units to max out the DMG buff from her Bonus Ability. Mortenax Blade and Cipher can debuff the enemies on their turn to add stacks for Acheron's Slashed Dream. Cipher can equip Lies Dance on the Breeze or Resolution Shines As Pearls of Sweat to have more chances of applying debuffs on an enemy. Mortenax Blade boosts Acheron's Ultimate Damage and gives her a general DMG amp, along with DEF shred to enemies for even more damage. You can run the team either sustainless or with a sustain character, as both compositions are viable. Sustainless teams are better with Welt since he can delay enemies and bring even more debuffs to the fight.
