Saber Alter Anime Vanguards is a powerful limited-time unit introduced during the Boss Rush event. With high scaling potential, team buffs, and devastating skills, Saber Alter is one of the most sought-after Curse units in the game. This guide will walk you through how to obtain Saber Alter, explain her abilities, and provide the full requirements to evolve her into Saber (Black Tyrant).
What is Saber Alter in Anime Vanguards?
Saber Alter is an exclusive Curse-type unit only obtainable through the Boss Rush event. Unlike regular units, Saber Alter can’t be pulled or crafted—she must be unlocked through a specific transformation process and drop system during the limited-time event. Once obtained, she becomes a strong PvE damage dealer with aura-based buffs and powerful attacks, making her a key asset for late-game content.
How to Get Saber Alter in Anime Vanguards
To unlock Saber Alter, you must participate in the Boss Rush event and follow this multi-step process:
1. Use Saber (King of Knights) in Boss Rush
Deploy the Saber (King of Knights) unit.
Place her near the enemy spawn area during the Boss Rush stage.
When placed correctly, she will transform into Saber AWE (Awakened Enemy Watcher).
Each active Saber AWE gives you a 0.75% chance of receiving Saber Alter at the end of the Boss Rush run.
2. Use Saber SWE for Bonus Chances
If you also have access to Saber SWE, deploying her will grant 3 additional roll chances for Saber Alter.
This significantly boosts your odds, especially if running multiple attempts during the event window.
3. Complete Boss Rush and Check Drops
At the end of the Boss Rush stage, Saber Alter will drop if RNG favors you. Because the chances are low, farming multiple runs using the correct setup is crucial.
Saber Alter Abilities and Strengths
Once obtained, Saber Alter becomes a top-tier PvE unit, known for her strong area effects and synergistic scaling.
Aura of Corruption (Main Skill)
Creates an area-of-effect zone around Saber Alter.
Slows enemies within the aura.
Speeds up nearby allies, improving their attack cycle.
Grants Saber Alter a damage increase up to 50%, scaling as she stays in combat.
This ability makes her a hybrid support-DPS unit, enabling both team utility and personal power scaling.
Strengths
Powerful damage buff for herself and attack speed boost for teammates.
Effective in PvE content due to aura-based debuff and crowd control.
Pairs well with units that rely on sustained DPS or area lockdown.
How to Evolve Saber Alter into Saber (Black Tyrant)
Saber Alter can be evolved into Saber (Black Tyrant), an even more powerful version with new mechanics and abilities.
Evolution Requirements:
1x Corrupted Visor (available from the event shop)
Essence materials (types and quantity vary)
30,000 Gold
5,000 Takedown
Once all materials are gathered, initiate the evolution through the unit menu.
New Abilities after Evolution
1. Summoned Servant
When Sokora is on the field, Saber (Black Tyrant) gains a synchronized bonus attack.
This interaction enables dual-unit synergy with linked strike animations.
2. Dark Excalibur
A powerful finishing move that deals AoE damage.
Applies burn effects to enemies.
After five successful attacks, Dark Excalibur receives a massive damage bonus.
These abilities push Saber (Black Tyrant) into top-tier raid performance, especially when paired with buff or synergy units like Sokora.
Final Thoughts
Saber Alter in Anime Vanguards is a high-value unit obtainable only through the Boss Rush event using the unique Saber AWE transformation mechanic. With her 0.75% base drop chance per Saber AWE and the 3 bonus rolls from Saber SWE, maximizing your chance requires a strategic unit setup and consistent farming.
Her skills—especially Aura of Corruption—make her invaluable in PvE for both damage scaling and team synergy. And with proper evolution into Saber (Black Tyrant), she gains access to Summoned Servant and Dark Excalibur, unlocking her full offensive potential.
Make the most of the limited-time event, gather the required evolution materials, and you’ll secure one of the strongest Curse units in Anime Vanguards.
