Best Characters for Blackmarrow Lantern in Genshin Impact
The Blackmarrow Lantern best characters are those who rely on Bloom and Lunar-Bloom reactions or scale with Elemental Mastery. Some of the top choices include:
- Lauma – This is her second-best weapon option after her signature Catalyst. It boosts her EM and Lunar-Bloom DMG, making it perfect for free-to-play players.
- Nahida – Increases her already strong reaction damage.
- Mona – Benefits from the EM stat and synergizes with Hydro reactions.
- Kokomi – Works well in Bloom and Hydro teams, boosting her supportive damage.
If you don’t wish to spend Primogems on limited 5-star Catalysts, Lauma Blackmarrow Lantern synergy makes it a must-craft weapon.
The Blackmarrow Lantern in Genshin Impact is a solid craftable weapon from the Nod-Krai series, offering powerful Bloom-focused buffs and a high Elemental Mastery stat. With easy access through its blueprint/diagram and relatively affordable crafting materials, it’s one of the best free Catalysts for Lauma, Nahida, Mona, and Kokomi.
Whether you’re a free-to-play player or just looking for a strong alternative to gacha weapons, this is definitely a Catalyst worth forging.
