Boss: Doppelganger10

The Doppelganger10 is a tricky boss encounter that mirrors Alucard's abilities, making it a test of your mastery over his moveset. This fight occurs in the Long Library, specifically in the large, open room near the save point and the Librarian's shop. Be prepared for a fast-paced battle where positioning and quick reflexes are key.

Preparation

Before engaging Doppelganger10, consider the following:

  • Equipment:
    • Weapon: A fast-hitting weapon like the Alucard Sword or the Muramasa is excellent for landing multiple hits during openings. If you have it, the Crissaegrim makes this fight trivial.
    • Shield: The Alucard Shield or Medusa Shield can offer some defense, but evasion is generally more effective.
    • Armor: Equip your best defensive armor, such as the Alucard Mail or Dracula Tunic, to mitigate damage from its attacks.
    • Accessory: The Necklace of J can provide a useful defense boost.
  • Sub-Weapons: The Holy Water is incredibly effective against Doppelganger10 due to its lingering damage. The Axe can also be useful for hitting it when it jumps.
  • Healing Items: Stock up on Potions and High Potions. While not strictly necessary if you play well, they provide a safety net.

Strategy

Doppelganger10 mimics many of Alucard's own attacks, making it a challenging but predictable opponent. Its primary moves include:

  • Sword Swings: It will perform basic sword attacks similar to Alucard's.
  • Dark Metamorphosis: It will occasionally use a dark version of Alucard's Dark Metamorphosis, causing damage if you touch it.
  • Hellfire: Expect it to cast Hellfire, launching three fireballs.
  • Summon Spirit: It can summon a spirit to attack, much like Alucard's own spell.
  • Wolf Form: It will transform into a wolf and charge across the screen.

Phase 1: Initial Engagement

  1. Start with Holy Water: As soon as the fight begins, throw a Holy Water. The lingering flames will deal significant damage while you get into position.
  2. Maintain Distance (Initially): Doppelganger10 is aggressive. Try to keep a medium distance to bait out its attacks and create openings.
  3. Jump Attacks: When it approaches, jump over it and attack from behind. This is a common tactic against many bosses, and it works well here.

Phase 2: Adapting to its Moves

  • Sword Swings: These are easy to dodge by jumping over or back-dashing. Counter-attack immediately after it finishes its combo.
  • Dark Metamorphosis: When it glows dark, move away quickly. This is a good opportunity to throw another Holy Water or use a projectile sub-weapon.
  • Hellfire: The three fireballs can be tricky.
    • If you're close, jump over the first two and duck under the third.
    • If you're far, simply back-dash or walk away from them.
    This is a great window for a few quick hits.
  • Summon Spirit: The spirit is slow and easily avoided. Focus on attacking Doppelganger10 while the spirit floats harmlessly.
  • Wolf Form: When it transforms into a wolf, it will charge across the screen. Jump over it to avoid damage. You can often get a hit in as it transforms or reverts.

General Tips

  • Aggression is Key: While caution is important, being overly passive will prolong the fight and increase your chances of making a mistake. Look for openings and punish them.
  • Sub-Weapon Usage: Don't be shy with your Holy Water. Its area-of-effect damage is fantastic for this fight.
  • Evasion: Master Alucard's back-dash and jump. These are your primary defensive tools.
  • Heal When Low: If your HP drops below 50%, use a Potion. It's better to be safe than sorry.

By following these strategies, Doppelganger10 will fall, allowing you to continue your journey through the Long Library and beyond!
