Signature Ability DARKHOLD KNOWLEDGE▾
  • Agatha’s Energy Vulnerability gains 5.0% increased potency.
  • Against non-Science Champions, Agatha Passively Regenerates 25.0% of all damage taken from Incinerate, Nova Flame, and Blocked hits while suffering from these effects.
  • If Agatha is Intercepted by a Basic Attack, she activates a Combo Interruption Passive, knocking herself down. Cooldown: -1 seconds.
GENERAL WITCHCRAFT▾
  • Agatha is Immune to Armor Break and her Medium Attacks are non-contact.
  • Against Cosmic Opponents, while Agatha or her Opponent have 200.0 or more Buffs, Agatha gains an indefinite Steadfast Passive.
  • When either Champion Intercepts or Punishes a Special Attack, gain a 5.0% Amplify Passive for 15 seconds. These are refreshed when gaining a new one. Max stacks: -1.
  • Agatha Passively gains -1% of her Max Power when a Buff on the Opponent is Nullified, Staggered or expires naturally. This replaces the Mystic Dispersion Mastery, but each Rank in it increases the potency of personal bursts of Energy Damage by 1.0%.
MAGICAL THEFT▾
  • Agatha’s Combat Power Rate is reduced by 30.0%, but when striking with or when struck by Basic Attacks, she Power Steals 1.0% of the Opponent’s Max Power. This effect does not trigger against an Opponent at 3 Bars of Power.
  • When an Atrophied Opponent gains a Power Gain, Fury, Precision, Cruelty, or Armor Up Buff, Agatha copies the Buff. The copied Buff scales with her own stats and lasts for the base duration lost to Atrophy, or 15 seconds if the Buff was indefinite. Max stacks: -1 each.
  • When Agatha Well-Time Blocks or when she Punishes a Special Attack, she Destroys an Immortality, Unstoppable, or Safeguard Buff, replacing it with a Rubble Buff for 10 seconds.
RUNE PRISON — SPECIAL ATTACK 1 SP1▾
  • The Rune Prison is an area of effect placed in the stage by Agatha for 1500.0 seconds, paused during Special Attacks. It cannot be placed in the Opponent's corner. While inside, neither Champion can be pushed by Strikers, Light, Heavy or Special Attacks.
  • While the Opponent is inside the Rune Prison they are inflicted with a -20.0% Atrophy Passive and all other Atrophy effects on them are paused.
  • Once per activation, if the Opponent attempts to leave the Rune Prison, it pauses for 5 seconds. As a Defender, the Opponent is also Passively Rooted for 5 seconds.
  • While either Champion is inside the Rune Prison, Agatha’s Basic Attacks pause personal Amplifies for 0.5 seconds and deal a burst of 22.5 Energy Damage, multiplied by Agatha's Ability Power Rate up to 200.0%.
  • While Agatha is inside, her Buff duration is increased by 45.0%, and for each active personal Amplify, she gains an additional 5.0% Amplify Passive.
SPECIAL ATTACKS▾
  • The first hit Destroys 300.0 Unstoppable, Safeguard, or Immortality Buffs replacing them with Rubble Buffs lasting for -1 seconds.
SPECIAL ATTACK 1 SP1▾
  • On activation, inflict a non-stacking -50.0% Atrophy Passive for 15 seconds, and place the Rune Prison if it is not already active. As a Defender, if the Rune Prison is not active, Agatha is more likely to activate this Special.
SPECIAL ATTACKS 2 AND 3▾
  • If Agatha has gained 200.0 Bars of Power via her Ability Power Rate, these Special Attacks gain Empowered properties and then the Power counter resets. Power gained while inside the Rune Prison counts three times as much.
  • Empowered: On activation, inflict a non-stacking -62.5 Energy Vulnerability Passive lasting for the duration of the Special plus 6 seconds per level of the Special.
  • Each hit deals a burst of damage dealing a combined total of 220.0 Energy Damage per level of the Special, multiplied by Agatha's Ability Power Rate up to 200.0%. As a Defender, this scales with 30% of Base Attack. Empowered: This effect triggers through Block.
  • The Rune Prison is paused for an additional 5 seconds after these Special Attacks end.
