What Makes Act 10.1 Challenging

Act 10.1 bosses enforce strict champion tag restrictions, limiting your roster options. Each boss has unique mechanics that punish common strategies: Brace for Impact prevents knockdowns, Unstoppable blocks standard pressure, and alternating root/reverse control disrupts your inputs during specials.

The key to clearing with minimal revives is matching the right counter to each boss, understanding one core mechanic per fight, and practicing the bait-and-punish rhythm specific to each encounter.

Core Strategy

Each boss has one dominant mechanic. Learn the counter rhythm for that mechanic, pick champions from the allowed tag pool that exploit it, and avoid strategies the boss specifically punishes.

Boss 1: Scarlet Witch (Sigil)

Scarlet Witch (Sigil)

Young Avengers tag only
Brace for Impact (can't be knocked down by heavy/SP final hits), buff nullify + power gain on her, enhanced parry.

Top Counter: America Chavez (best pick - strong power control, doesn't rely on buffs). Backup: Patriot.

Fight Rotation

  • SP1 bait: Dash in during her rock-lift animation, hold block through the hit, then immediately punish with heavy or basics to remove Brace
  • Avoid buff spam: She nullifies buffs and gains power toward SP2. Skip parry, let heavies hit your block and recover with big SP2s
  • Rhythm: SP1 bait, punish, repeat. Finish with SP2 when she's low

Common Mistakes

  • Relying on buff-dependent champions (her nullify removes buffs and gives her power)
  • Trying to parry constantly (enhanced parry makes this unreliable)
  • Rushing heavies without removing Brace first (wastes damage and time)

Boss 2: Hulk Ragnarok

Hulk Ragnarok

#God tag only
Boxed-in (must stay close, no distance), frequent Unstoppable + stun immune, multiple triggers.

Top Counter: Valkyrie (best - pierce ignores Unstoppable once built). Backup: Serpent or Taskmaster for durability.

Fight Rotation

  • Stay aggressive and close: Boxed-in punishes distance. Bait SP1/SP2 and punish to gain 6s Grit passive (ignores his Unstoppable)
  • Use Matador node: Punishing his specials gives you a full power bar. Lean into baiting them
  • Rotation: Bait special, punish for Grit, attack freely while active, repeat. Valkyrie simplifies this massively

Common Mistakes

  • Backing off too far (boxed-in mechanic punishes distance)
  • Trying to parry through Unstoppable or stun immune
  • Not baiting specials for power and Grit generation

Boss 3: Hulkbuster (Toughest Fight)

Hulkbuster

Villain + Gamma tags
Alternating root/reverse control on specials, Made of Rubber (debuffs reduce reflect/damage taken), Obsolete Charge (parry shield), Shock (guaranteed crits on his hits).

Top Counter: Joe Fixit (favorite - debuffs + sustain). Backup: Immortal Abomination (poisons/burns), Leader.

Fight Rotation

  • Track the gray icon: Watch the icon under your health bar. It swaps root/reverse control every special
  • Keep him on SP1: Easier to dex and control. Bait SP1, dex the mechanic, apply and maintain debuffs to lower his reflect
  • Parry management: First parry removes Obsolete Charge, second parry stuns. Manage Shock carefully (Willpower helps)
  • Patience rhythm: Bait SP1, dex, debuffs up, attack, repeat. Steady play wins this fight

Common Mistakes

  • Ignoring the alternating root/reverse control mechanic (leads to quick deaths during Shock)
  • Rushing openings without debuffs applied (low damage due to Made of Rubber)
  • Using non-debuff Gamma/Villain champions (low value without debuff application)
  • Getting caught in reverse control during Shock windows
