While each weapon key in Genshin Impact accounts is usable, because of the shared destiny with characters and also the element system, there's a ranking for them.
The weapons of Genshin Impact might not be as impactful because of the seven core elements, but they're still an important part of combat using their own ranking. Currently, five weapon types are usable hanging around, each using its unique fighting style that sees slight alterations with respect to the character wielding them. A perfect illustration of this may be the Bow users Ganyu and Yoimiya. Ganyu does her best damage by charging her attacks, while Yoimiya really wants to fire rapidly. Minor differences such as these keep the weapons feeling fresh, which has been crucial using the lack of new weapon-type additions.
The hardest part of judging Genshin Impact's weapons is they often depend on the characters with them, therefore the most potent weapons at a moment are the ones that belong to whatever character is strongest in those days. Characters like Hu Tao, Raiden, and Zhongli dominating the meta makes Genshin Impact's best Polearm users a well-known choice locally. This is also the downside of the weapon system because the weapons are susceptible to the characters which are made around them instead of their individual prowess.
Claymores
Claymores in many cases are the forgotten weapon of Genshin Impact. This is mainly because of the lack of high-value characters and also the inflexibility it has using the game's elemental reaction system. Claymores in many cases are slow and for physical damage compared to what they are elemental, causing them to be detrimental in teams seeking to make constant reactions. Overall, when players are seeking to put teams together, it's hard to justify utilizing a Claymore unless the character it's equipped with is particularly strong.
The other problem with Claymores is the insufficient powerful characters it's gotten. There was a time when Diluc was one of the best DPS choices, but it has passed. Eula is really a decent Claymore user, but besides her very long time without a rerun, she's mainly an actual DPS. Itto can also be decent, but he requires a specific pure Geo team built around him to become usable. Besides those big names, others like Noelle, Beidou, and Dehya have such niche uses that they in many cases are not worth using over other characters.
Catalysts
Catalysts really are a weird one, as while their basic attack pattern is comparatively simple and dull, they succeed in strong characters. From a pure gameplay perspective, Catalysts are easy and not exceptionally fun to make use of. However, they've one unique function which makes them useful when you are in teams. Catalysts' normal and charged attacks do elemental damage, meaning those are the only normal attacks that are not altered by the capability can trigger elemental reactions.
The greatest strength of Catalysts continues to be the characters that comprise some of the best supports hanging around. The free character Barbara creates a tremendous early-game healer/Hydro applicator. Whereas within the endgame, characters like Mona, Nahida, Sucrose, and Kokomi become crucial people in certain team comps. Though Catalyst users won't be known for their damage, the supportive bonus they provide teams is almost unmatched.
Swords
Swords would be the perfect illustration of an overall great weapon in Genshin Impact. They are quick, have some fun combos, and do adequate damage that elemental reactions aren't always necessary. Some of the most powerful weapons hanging around are a part of this class, plus they can make a realm of difference. However, it's the characters that make Swords as strong as they are.
Swords have come from the game's best and many comprehensive selections of characters. Supports like Bennet, Kazuha, and Xingqiu are constantly popular picks that amplify a team's damage. Genshin's Sword weapon type can also be home to some of the best DPS characters like Ayaka, Nilou, Ayato, and Alhaitham. Overall, this weapon provides a variety of characters that may fill multiple roles in teams and become used in the highest tier of combat.
Bows
Bows have some of the most flexible gameplay in most of Genshin Impact. At first, they might seem like the standard weapon that fires basic and charged attacks, but they have the potential for a lot more. Small combos are intertwined into the basic attacks to ensure they are more appealing, while charged attacks are going to be infused using the characters' elements. Bows are also the only long-range weapon from the five, which makes them crucial for specific situations.
Bows are another weapon class that is the place to find a flexible and strong cast of characters. This includes four main standouts for DPS in Yoimiya, Ganyu, Childe, and Tighnari. As well as some support options in Yelan, Venti, and Fischl. Bows' wide selection of attack patterns, characters, and powerful 5-Star weapons make them one of the premier weapon choices in Genshin Impact.
Polearms
Polearms have rightfully earned their spot because the top weapon in Genshin Impact because of fantastic gameplay and high-tier characters. Along with having a far reach, they are able to quickly dish out significant physical damage and charged attacks that pierce through multiple enemies. Polearms also provide the longest selection of any melee weapon hanging around, putting them above Swords and Claymores. Just from gameplay mechanics alone, Polearms might be considered the ruler of weapons in Genshin Impact.
The characters which use this weapon type, of which there are many, are another strong point the weapon has. Some of the best DPS choices in Hu Tao, Raiden, Cyno, and Xiao are high-usage choices that may deliver severe damage. This class also offers some great support options like Raiden - who are able to be used both in roles - Zhongli, Xiangling, and Shenhe. Polearms have become a well-known choice locally, with strong gameplay mechanics and character choices such as these, it is obvious why.
All the weapons in genshin impact accounts are unique and fun themselves, causing them to be all viable right players. Some have gotten a bit more attention than others, which has created this gap between each type. So, while there's a clear ranking from the worst to the best weapons in Genshin Impact, the gaps between them might not be as large as fans assume.
