As a reporter for The Steambird who’s always chasing the latest scoop across Fontaine, I’ve learned that having the right tools for the job is essential—both in journalism and in combat. Being Genshin Impact’s first Four-Star Cryo catalyst user means my trusty camera isn’t just for capturing moments, but also for freezing enemies in their tracks while providing crucial healing support to my team through my Elemental Burst. Choosing the perfect catalyst from the massive arsenal available can dramatically change how I perform on the battlefield, whether I’m focusing on pure healing, energy regeneration, or even dealing some damage myself.
Let’s start with the most accessible option that every player likely has multiple copies of: Thrilling Tales of Dragon Slayers. This humble Three-Star catalyst has been helping teams since the game’s launch, and it still finds relevance in my loadout today. With its HP substat and incredibly powerful passive—granting the next character a 48% ATK boost for ten seconds after I switch out—it transforms me into a support buffer rather than just a healer. I particularly enjoy using it in freeze teams where we don’t have Bennett’s massive ATK buff available. The catch? It doesn’t enhance my personal healing or damage at all, making it purely a team-support choice.
When I’m struggling to keep my Elemental Burst ready for those critical healing moments, Favonius Codex becomes my go-to solution. The 45.9% Energy Recharge substat feels like a lifeline, and landing critical hits to generate those precious energy particles for the whole team creates such satisfying gameplay loops. Building enough Crit Rate to reliably trigger its passive requires some artifact optimization, but the payoff is worth it—I can generate particles with my camera skills, then quickly swap to funnel energy to teammates who need their bursts ready. This weapon turns me into an energy battery for the entire party.
Fontaine’s blacksmith offered me Flowing Purity, a craftable option with an interesting but tricky mechanic. The 16% Elemental DMG bonus upon using my Elemental Skill feels fantastic, but that Bond of Life debuff creates an interesting dilemma—I need to heal it away to unlock the additional damage buff. Since my only healing comes from my Elemental Burst, this weapon forces me to prioritize Energy Recharge even more than usual. When everything aligns perfectly though, the damage output becomes noticeably better while still maintaining solid healing capabilities.
I was fortunate enough to obtain the Oathsworn Eye during that limited-time event, and it feels almost tailor-made for my playstyle. Using my camera skill (Elemental Skill) triggers a massive 48% Energy Recharge boost for ten seconds, ensuring my burst is always available when my team needs healing most. The ATK substat also contributes to my healing scaling, making this weapon a beautifully balanced option. It’s such a shame this catalyst isn’t more widely available, as it represents one of the most synergistic four-star choices for my kit.
For those days when I want to contribute more than just healing, Skyward Atlas offers a premium five-star experience. The massive ATK stat and substat directly boost my healing numbers since my burst scales with ATK, while the passive provides that sweet 12% Elemental DMG bonus and occasional extra damage instances. This catalyst allows me to build a hybrid Charlotte who can both sustain the team and deal respectable damage with normal attacks. The feeling of watching my healing numbers climb alongside my damage output is uniquely satisfying.
Memory of Dust presents perhaps the most specialized playstyle requirement among all my weapon options. To fully utilize its potential, I need to constantly maintain a shield on my character—thankfully, teammates like Zhongli or Layla make this manageable. The stacking ATK buff (up to 20%, doubled to 40% with a shield) creates exponential growth in both my damage and healing capabilities. There’s something thrilling about fighting from within the safety of a shield while watching my camera’s Cryo applications hit harder with each consecutive attack.
But if we’re talking about pure healing optimization, Prototype Amber remains the undisputed champion even among five-star options. Available from any blacksmith, this accessible four-star catalyst provides exactly what a healer needs: energy regeneration and party-wide healing. The passive that restores 12-18 energy over six seconds perfectly complements my burst’s cost, while the additional 6% HP healing for the entire party stacks beautifully with my own healing capabilities. It’s remarkable how this craftable weapon consistently outperforms premium options for healers—proof that sometimes the simplest tools are the most effective.
Each weapon choice reflects a different approach to combat:
-
🛡️ Team Support Focus: Thrilling Tales, Favonius Codex
-
⚔️ Hybrid Damage/Healing: Flowing Purity, Skyward Atlas
-
❤️ Pure Healing Optimization: Prototype Amber
-
🔄 Energy Management: Oathsworn Eye
-
🛡️⚔️ Specialized Synergy: Memory of Dust
What I’ve discovered through my travels is that the ‘best’ weapon depends entirely on my team composition and combat objectives. In quick-swap teams where I’m mainly providing Cryo application and burst healing, Favonius Codex or Prototype Amber serve me perfectly. When I’m the primary sustain in a team with strong shields, Memory of Dust unlocks incredible potential. And when I want to feel more like an active combatant rather than just support, Skyward Atlas lets me contribute meaningful damage while still keeping everyone healthy.
The beauty of being a catalyst user is this versatility—I can adapt my weapon choice to whatever situation my reporting (or adventuring) requires. Whether I’m documenting ancient ruins or battling the Fatui, having the right catalyst makes all the difference between a successful expedition and needing to make an emergency retreat. My camera captures the truth, but my chosen weapon ensures I live to report it.
