Hades 2 Hecate & Scylla and the Siren Adversary Oath Detailed Guide: From Beginner to Expert
1. 🔥 Hecate "Rival's Vow" Guide: Phase Mechanics, Skill Responses, and Minion Management
  • Basic Logic: Hecate has three phases, and you need to clear witch minions each time she enters an invulnerable state.
  • Important Mechanic: Dealing too much damage in a short time will trigger Hecate to teleport and reset the rhythm.
  • ⚠️ Starting Move: Avoid being greedy with attacks. Use invincibility frames to dash through the "Dark Pulse Circular Wave" before attacking.
  • Dark Wave: Run in a large circle, keeping your distance from Hecate to avoid being hit by the edge of the wave.
  • Half-Moon Blade Slash: Observe the torch posture to determine whether it's a single or double half-moon blade. Dodge left or right for a single blade, and dash through Hecate for a double blade.
  • Clone Attack: Look for the real body that walks and moves, or observe the main body with curse/status markers.
  • Minion Clearing Phase: Stand in the corner of the field, dodge projectiles with small movements, and prioritize clearing the witch minions.
  • Flying Howl: When you see Hecate flying, increase the distance, and dash through the circle the moment she lands.
  • ⚠️ Sheep Ball: Focus on the sheep ball and maintain rhythmic dashes to dodge, avoiding chaotic movements.
  • Machine Gun Half-Moon Blade Barrage: Stay close to Hecate's face to dodge a large number of projectiles and deal damage.

2. 🌊 Scylla & the Sirens "Rival's Vow" Guide: Prioritize Crowd Control, Divide and Conquer
  • Core Concept: Clear the field first, then attack the main target.
  • Starting Position: Run to the lower left corner of the field to avoid the shell dash and make the drummer's first wave of attacks miss.
  • Priority Target: Take down the tentacles near the drummer first to reduce pressure.
  • Tentacle Response: Stay close to the tentacles, and dash to dodge the moment their bodies lean back and turn white, and use the stagger time to deal damage.
  • Drummer Roxy: Respond to the large circle mechanic (run in/out), and attack up close when the drumbeat attacks spread from the inside out.
  • ⚠️ Guitarist: Watch out for the stun attack wave to avoid being stunned and taking more damage.
  • Scylla: After the shell dash ends, she will spit out spiky balls, so it is recommended to dash through them.
  • After 50% Health: Maintain the priority of clearing tentacles → attacking the drummer, and avoid being impatient.
  • When the Field is Chaotic: Try to move to the edge of the field to avoid most projectiles.
  • Final Phase: After Scylla activates the invulnerable shield, stick to her and burst damage as much as possible before the mobs spawn.
