If you’re planning to build Mizuki as a main DPS or support, choosing the best weapon will unlock her full potential. In this guide, we’ll go over the top Catalyst choices for Mizuki, ranging from premium 5-star options to solid F2P alternatives.

Best Weapons for Mizuki – Ranked

1️⃣ Sunny Morning Sleep-In (Best in Slot)

⭐ 5-Star | High Elemental Mastery & Buffs

• Base ATK (Lv 90): 542
• Secondary Stat (Lv 90): 265 Elemental Mastery
• Passive Effect:
  • +120 EM for 6 seconds after triggering Swirl.
  • +96 EM for 9 seconds after an Elemental Skill hit.
  • +32 EM for 30 seconds after an Elemental Burst hit.
  • Total bonus of up to 248 additional EM.

✅ Why It’s Best for Mizuki:
✔ Massive Elemental Mastery boost from both sub-stat and passive effect.
✔ Boosts all aspects of Mizuki’s kit, maximizing Swirl damage.
✔ Synergizes with other Catalyst users who rely on EM.

❌ Downsides:
✖ Limited availability – only obtainable through the weapon banner.

🛠 Verdict: Mizuki’s signature weapon is her best option—hands down. If you’re planning to invest heavily in her, this Catalyst is worth pulling for.

2️⃣ A Thousand Floating Dreams

⭐ 5-Star | Strong Elemental Mastery Buffs

• Base ATK (Lv 90): 542
• Secondary Stat (Lv 90): 265 Elemental Mastery
• Passive Effect:
  • If team members share the same element, +32 EM per stack (max 3 stacks).
  • If team members have different elements, +10% DMG Bonus per stack.
  • All teammates (except wielder) gain +40 EM.

✅ Why It’s Great for Mizuki:
✔ High Elemental Mastery boost from both passive and sub-stat.
✔ Provides team-wide buffs, which is helpful for reaction-heavy teams.
✔ Great alternative if you already own it (e.g., from Nahida’s banner).

❌ Downsides:
✖ Not designed specifically for Mizuki, so it’s not fully optimized for her.

🛠 Verdict: A strong alternative to her signature weapon, offering consistent EM bonuses and good team synergy.

3️⃣ Sacrificial Fragments

⭐ 4-Star | Best Budget Option

• Base ATK (Lv 90): 454
• Secondary Stat (Lv 90): 221 Elemental Mastery
• Passive Effect:
  • 40%-80% chance to reset Elemental Skill cooldown after hitting an enemy.

✅ Why It’s Good for Mizuki:
✔ Boosts Elemental Mastery, enhancing Swirl damage.
✔ Cooldown reset allows more Skill casts, extending Dreamdrifter State.
✔ Easier to obtain and refine compared to 5-star weapons.

❌ Downsides:
✖ Lower Base ATK compared to 5-star options.
✖ Random cooldown reset chance—not 100% reliable.

🛠 Verdict: A top-tier 4-star option that helps increase uptime on Mizuki’s Elemental Skill, making her rotation smoother.

4️⃣ Starcaller’s Watch

⭐ 5-Star | High Elemental Mastery, But Wasted Passive

• Base ATK (Lv 90): 542
• Secondary Stat (Lv 90): 265 Elemental Mastery
• Passive Effect:
  • +100 Elemental Mastery.
  • “Mirror of Night” effect (grants +28% DMG for 15 sec after creating a shield).

✅ Why It’s Decent for Mizuki:
✔ High Elemental Mastery from sub-stat and passive.
✔ More reliable than other non-signature 5-star weapons.

❌ Downsides:
✖ Passive is completely wasted since Mizuki does not create shields.
✖ Only viable for pure Elemental Mastery stacking—no added utility.

🛠 Verdict: A good EM option, but the wasted passive makes it suboptimal for Mizuki compared to other 5-star choices.

5️⃣ Mappa Mare (Best Free-to-Play Choice)

⭐ 4-Star | Solid F2P Alternative

• Base ATK (Lv 90): 565
• Secondary Stat (Lv 90): 110 Elemental Mastery
• Passive Effect:
  • Triggering an Elemental Reaction grants +16% Elemental DMG Bonus for 10 sec (max 2 stacks).

✅ Why It Works for Mizuki:
✔ Craftable at the Blacksmith—no need to pull from banners.
✔ Decent Elemental Mastery boost.
✔ Elemental DMG bonus increases overall DPS.

❌ Downsides:
✖ Lower Elemental Mastery than other options.
✖ Relies on reaction uptime for maximum effect.

🛠 Verdict: The best free-to-play weapon for Mizuki, offering reliable Swirl damage boosts.

🔹 Wandering Evenstar – Decent Elemental Mastery boost and slight ATK scaling for the team.
