Boss Attributes

Skill descriptions are shared across all Memorial Arena brackets. But the exact boss stats are (vastly) different across brackets.

C Rank

• Overdrive: The mech accumulates Overload energy based on the number of hits taken and HP loss. Overload energy quickly dissipates if not attacked for 2s. At full Overload energy, Heimdall enters Overdrive mode for 20s, during which it gains considerable DMG and ATK Speed boost.
• Overdrive DEF: Heimdall gains 45% Total DMG Reduction during Overdrive Mode.
• Iron Wall: Energy: 2 slots. Heimdall activates its massive shield to create a Defensive Force Field that can only be shattered by super heavy attacks (such as Valkyrie Chariot's Gravity Shatter). Force Field active: When attacked by opponent less than 5 meters away, Heimdall ends defensive stance and counterattacks. If the field is broken, lose 1 Energy slot and suffer 5% higher Total DMG Multiplier from hits taken. Stacks up to 2 times. While Energy is depleted, Heimdall takes 20% more Total DMG, and Overdrive DEF will not trigger.

SSS Rank

• Iron Wall: Heimdall has Iron Wall, which grants DMG reduction and high resistance against control effects. However, the Iron Wall is weakened by Ignite DMG or Bleed DMG.
  Tip: Ignite and Bleed skills are recommended to wear down Heimdall's Iron Wall, which inflicts Vulnerability for some time after breaking.
• Magnetic Restriction: During its phase change, Heimdall activates the magnetic field system to generate continuous magnetic interference. If it detects the player attacking in the magnetic field, it will release magnetic resonance to immobilize all characters on the field for some time.
• Net of Annihilation: During its phase change, Heimdall activates the Net of Annihilation. Interwoven laser beams sweep the field, dealing DMG to characters in the way.
• Charging Overdrive: After its phase change, Heimdall will start charging, repairing itself and activating Overdrive mode in the process. Ignite DMG and Bleed DMG dealt during which is irreversible, and inflicts Vulnerability in the Overdrive mode to come.
• Overdrive Mode: In its second phase, Heimdall enters Overdrive mode and attacks more relentlessly. In the meantime, Iron Wall is also affected by Overdrive mode, and each attack from a Bleeding or Ignited Heimdall damages Iron Wall.

Trivia

• Heavy ATK advantage only applies at C~SS Rank; Ignite and Bleed advantage only applies at SSS Rank.
