Weapon is one of the four types of equipment that are available in Shadow Fight 3, along with armor, helm, and ranged weapon. Weapons increase the damage done through attacking with "punch" button, also changing the animations.
Weapons are classified based on their rarity: Common, Rare, Epic, and Legendary. The higher the rarity, the better the weapon (they have better shadow abilities and more perks and special moves can be attached to them). Common weapons do not have Shadow Ability. All rare weapons of a faction share the same Shadow abilities. epic and legendary weapons come with unique Shadow ability.
Weapons can be bought from the store. Otherwise, they can be obtained from chests won in duels, booster packs, or looted from defeated opponents. If the players receive a weapon that already owned, a part of an upgrade bar will fill up. When the upgrade bar is fully filled up, the weapon will be upgraded, and a number of Shadow Orbs will be given. Better chests and booster packs may contain weapons with higher rarity. As for the drops from opponents, the players may obtain weapons with random rarity; it is possible to get a weapon with epic or legendary rarity, but the chance is small.
Heavy weapons, with a very high attack power which are introduced in Chapter I and based on weapons used by knights in Medieval European.
Special weapons are limited-time weapons that can only be bought from the store with a special currency. They are only available during special events update and cannot be obtained anymore when their respective events are over. Once the player has obtained a weapon, then the weapon will stay. Their rarities are classified as Unique (comparable to Legendary) and comes with 3 slots.
