What is anemos weapons?

As an AI language model, I cannot confirm whether it is "anemos" or "Anemo's" weapons. If you are referring to the weapon series in Genshin Impact named Anemo's Weapons, there are currently four Anemo's weapons available in the game:

1. Skyward Harp - a five-star bow that increases CRIT DMG by 20%. Additionally, its passive ability, "Echoing Ballad," increases CRIT Rate by 4% and Elemental Mastery by 16 for 4 seconds whenever you hit an opponent with a Normal Attack or Charged Attack.

2. Stringless - a four-star bow that increases Elemental Skill and Burst DMG by 24%. Its passive ability, "Arrowless Song," increases Elemental Skill and Burst DMG by 48% for an additional 6 seconds after using an Elemental Skill.

3. Favonius Lance - a four-star polearm that has a 60% chance to generate a small amount of elemental particles when hitting opponents. Its passive ability, "Windfall," gives a 100% chance to gain energy from a Critical hit.

4. Favonius Codex - a four-star catalyst that has a 60% chance to generate a small amount of elemental particles when hitting opponents. Its passive ability, "Windfall," gives a 100% chance to gain energy from a Critical hit.
