Is Rainslasher Good for Beidou in Genshin Impact? A Deep Dive

The short answer? Rainslasher can be a decent option for Beidou in Genshin Impact, but it’s highly situational and not her best-in-slot weapon. While it boasts a passive that increases damage against enemies affected by Hydro or Electro, this benefit is entirely dependent on your team composition and the enemies you’re facing. To fully understand if Rainslasher is a good choice for your Beidou, we need to delve into the nuances of her kit, team synergy, and the weapon’s strengths and weaknesses.

Rainslasher: A Double-Edged Sword

Rainslasher is a 4-star claymore obtained through wishes, making it relatively accessible. Its primary appeal lies in its passive ability: increasing damage against opponents affected by Hydro or Electro by a substantial percentage (scaling from 20% to 36% at refinement level 5). Furthermore, its secondary stat is Elemental Mastery, which can boost the damage of elemental reactions.

However, this is where the caveats begin for Beidou. Rainslasher’s passive requires that enemies are always affected by Hydro or Electro to provide its damage bonus. This puts the weapon in a very niche spot, limiting its effectiveness to teams that consistently apply these elements. It’s not a weapon you can just slap on Beidou and expect great results, unlike her other viable weapons.

Why Rainslasher Can Work

Despite its limitations, Rainslasher isn’t entirely useless for Beidou. Here’s why it can be a good option:

• Electro-Charged Team Comps: If you are running a Beidou team composition that focuses heavily on Electro-Charged reactions (using a Hydro character like Xingqiu, Yelan, or Childe), the Rainslasher passive can be constantly active, boosting Beidou’s damage output considerably.
• Elemental Mastery Boost: For these electro-charge focused team comps, the Elemental Mastery substat can be a significant boon for the overall team’s reaction damage.
• Accessibility: As a 4-star weapon, it’s much easier to obtain and refine Rainslasher than 5-star alternatives, making it a readily available option for players on a budget.

Why Rainslasher Falls Short

The Rainslasher has several drawbacks when used on Beidou:

• Conditional Passive: The primary disadvantage of Rainslasher is its conditional passive. If you are not fighting enemies consistently afflicted with Hydro or Electro, you are essentially using a claymore without a passive.
• Missed Potential: Beidou often excels as an off-field Sub-DPS, and Rainslasher’s focus on on-field damage doesn’t capitalize on her best strengths. Characters better suited for on-field damage can utilize Rainslasher to better effect.
• Alternatives are Superior: Compared to other 4-star claymores like Serpent Spine (which boosts her damage without condition) and Favonius Greatsword (which facilitates better energy regeneration for Beidou’s high-cost ultimate), Rainslasher often falls behind in overall usefulness. Even 5-star options, like Wolf’s Gravestone, outperform it by a large margin.
• Lack of ATK: Rainslasher’s base ATK isn’t particularly high, which limits overall damage potential without the conditional passive bonus being active.

Beidou’s Kit: Why Rainslasher is a Mixed Bag

Beidou’s playstyle is unique. Her Elemental Skill, Tidecaller, allows her to counter attacks for massive Electro damage, while her Elemental Burst, Stormbreaker, creates a powerful Electro shield that deals damage and enhances the attacks of her team.

Given that Beidou’s damage often comes from her Burst’s Electro damage and Tidecaller counter, the conditional damage boost from Rainslasher doesn’t consistently impact her main damage-dealing abilities. It’s only her basic attacks while her burst is active or her Tidecaller counter that benefit from the Hydro/Electro debuff, which might make the passive less than ideal for an off-field character.

Optimal Builds for Beidou

When looking at optimal Beidou builds, most of the time, you want to focus on her being a Sub-DPS character. While she can fulfill the role of a main DPS, her burst allows her to do incredibly high off-field damage and enables her to cause a ton of reactions. Artifacts and weapons that boost Electro DMG and energy recharge are usually prioritized. The best artifact set for Beidou is often the Emblem of Severed Fate, and alternatives are using 2pc Thundering Fury and 2pc Noblesse Oblige.

Rainslasher does not provide the needed energy recharge that Beidou requires, and the focus on a conditional elemental reaction damage might not be the most efficient way to play her.

Conclusion

In summary, while Rainslasher can be a functional weapon for Beidou, it is far from her ideal choice. Its dependence on Hydro or Electro application makes it too situational for consistent performance. Superior options exist that will give you more dependable results. If you don’t have anything else, and you are running an electro-charged team composition with her on the field, it might be a serviceable option. Otherwise, save it for someone else.

Frequently Asked Questions (FAQs)

1. Is Rainslasher useful for Beidou’s shield?
