"This Stand appears as a cannon on the user’s arm. It can convert minerals into Stand power and blast it at its foes, like a battery that uses metal as fuel. It can be detached if necessary. As far as Stands go, its pure destructive capability is top of the line." (In-Game Description)
"You are lively and flexible, but passionate about your likes and dislikes, and strongly opinionated. Sometimes your temper gets the best of you, and you'll lose your head over the tiniest slight. However, you're empathetic and always an open book when it comes to feelings, so people find you easy to talk to. You trust your heart rather than your head, often letting your emotions carry you away." (Personality Evaluation)
Quicksilver is a "glass cannon" with high power output but low defense and hit rate and high SP consumption. The risk is high, but so is the reward. Its array of strong attacks that hit all enemies, as well as its range, make it ideal for early- and late-game grinding. In addition, it can consume the Scrap Metal you can buy in Calcutta and Edfu for SP recovery.
Quicksilver's normal attack is a physical, non-ranged attack that hits one enemy.
