What it is
Keqing Mains (KQM) is a website dedicated to character guides and theorycrafting for Genshin Impact, maintained by a team of recognized theorycrafters in the community. Unlike technical tools like Genshin Optimizer that help you optimize what you already have, KQM tells you what objectives to pursue: what stats to target, what weapons are best, what team comps work, and why.
Each character in the game has a complete guide that includes multiple builds depending on role (main DPS, sub DPS, support, healer), detailed rankings of weapons and artifacts, target stats, talent priorities, optimal rotations, recommended team comps, and analysis of each constellation's impact.
The name has historical origins: KQM was born as a Discord dedicated to Keqing theorycrafting (one of the game's initial characters). Over time it expanded to cover all characters and became the most respected community theorycrafting hub in Genshin.
What problem it solves
Genshin Impact has a combat system with many variables: target stats (crit ratio, ER, EM), elemental reactions, talent scaling, character synergies, artifact sets with specific bonuses, weapons with passive effects. For each character, there are dozens of possible configurations, but only some are optimal.
KQM solves this by delivering guides curated by theorycrafters who have tested, calculated, and validated optimal configurations. When you read Hu Tao's KQM guide, you're not reading casual opinion: you're reading the result of hours of community testing, mathematical simulations, and expert consensus.
For a player, this means: instead of testing 10 different builds to find the good one, you go directly to the correct build and spend your time reaching it.
What people use it for
Specific character builds: the central use case. You have a character and want to know exactly how to build them. You go to their KQM guide and get detailed recommendations with explanations of the why behind each decision.
Deciding between weapon options: is Aqua Simulacra from wishes or f2p Stringless better for my Yelan? KQM ranks weapons available for each character with cost vs damage trade-off analysis.
Finding team comps: which characters fit with Raiden Shogun? KQM has a catalog of popular team comps with explanations of synergies.
Understanding deep mechanics: KQM has "Theorycrafter Library" with articles on how complex reactions work, elemental damage math, stat scaling, and other advanced topics. Useful for players who want to understand why something is optimal, not just what the answer is.
Updated tier lists: character rankings by category updated according to meta. Useful for deciding which characters to invest limited resources in.
Deciding whether to pull constellations: each character has 6 constellations that improve their capabilities. KQM analyzes each one's impact with priority tier (essential, very strong, nice-to-have). Helps you decide if it's worth spending extra primogems on C2 or C6.
Quickswap and advanced rotations: for advanced players, KQM has specific guides on quickswap (rapidly switching between characters to maximize damage). It's niche content but respected.
What sets KQM apart
There are other Genshin guide sites (Genshin Lab, Game8, various fandoms). What differentiates KQM:
Team of recognized theorycrafters: guides are written and reviewed by people with established reputation in the community. They're not anonymous writers copying information, they're theorycrafters who also participate in Discord, Reddit, and community debates.
Internal review process: each guide goes through review before publishing. This ensures consistent quality and reduces errors.
Depth of explanation: KQM doesn't just tell you "use this set", it explains why this set is better than alternatives, in what cases the alternative is worth it, and what the specific mathematical trade-off is.
Active maintenance: when a character receives buffs/nerfs, when new weapons come out, when new mechanics are discovered, guides update. KQM maintains a visible changelog of when each guide was updated.
Audience tags: many guides include "F2P-friendly" versions in addition to the optimal version. Recognizes that not all players have access to 5-star weapons and proposes viable alternatives.
Notation system: KQM has a standardized notation for describing rotations that has been adopted by the broader community. Makes guides more precise and comparable.
How it complements other tools
KQM in isolation is a guide. But its real value emerges in combination with technical tools:
Typical workflow of a serious player:
Decide which character you want to improve.
Read the KQM guide to understand what stats to target, what target weapon, what artifact set.
Go to Genshin Optimizer and input the objectives KQM recommended.
Genshin Optimizer shows you the optimal combination of your current artifacts to reach those objectives.
If you need to farm more, plan with available resin.
If pulling new weapon, verify if you have enough primogems in Paimon.moe.
KQM defines the destination, other tools help you get there.
Honest limitations
Only available in English. This is the most significant limitation for Spanish-speaking audiences. KQM has no localization to Spanish or other languages. Technical terms (talents, scaling, reactions, weapons) are all in English. For Spanish users who don't handle English terminology, there's a real barrier.
Doesn't replace executing rotations well. KQM shows you the optimal rotation in notation, but executing it in-game requires player mechanical skill. Knowing Hu Tao has a specific rotation and being able to execute it consistently are different things.
Bias toward optimal builds. Guides typically assume you want to maximize performance. For casual players who just want "my character to work" without obsessing over the last 5% of DPS, KQM can feel intimidating. The information is there, but the tone assumes seriousness.
Editorial coverage can be delayed. When a new character comes out, KQM frequently publishes a preliminary guide day one, but the definitive guide can take weeks while the team tests and discusses. Early access guides can be significantly revised.
Some guides have uneven depth. Very popular characters (Hu Tao, Raiden, Nahida) have massive guides with everything covered. Less popular characters can have simpler guides. It's natural but something to be aware of.
Dense theorycrafting for beginners. The "Theorycrafter Library" section has genuinely dense articles on math and mechanics. You don't need to read it to use character guides, but if you peek, it can be intimidating.
How to get started
Doesn't require installation, registration, or an account. You go to keqingmains.com from any browser.
For your first time, practical recommendation: go directly to the guide of the character you play most. The structure is consistent between guides, so learning one teaches you to read all. Start with "Best Weapons" and "Best Artifacts" sections — that gives you the most actionable information immediately.
As you familiarize, explore other sections of the guide: "Talent Priority" to know what to upgrade first, "Constellations" to decide if pulling character extras, "Team Compositions" for team ideas.
If you're interested in deeper theorycrafting, "Theorycrafter Library" has excellent articles on mechanics. But only enter there once you handle the basics — for beginners it's overkill.
To get maximum benefit, combine KQM with Genshin Optimizer (KQM defines what to look for, GO helps you reach it) and with tier lists to decide which characters to prioritize. That combination is the standard toolkit of serious Genshin players.
