Gold Experience is one of the most versatile Stands in the series. It has the ability to create and manipulate life, which Giorno most often uses to produce plants and small animals. Both can be used for a variety of purposes ranging from disguise to tracking origins. As a short-ranged Power-type, it is also capable of unleashing a rapid barrage of punches, which Giorno uses almost exclusively with lethal intent.
Gold Experience Requiem is obtained after Giorno pierces Gold Experience with the Stand-creating Arrow. It has the ability to turn the opponent's willpower and actions to zero. Whoever is killed by Requiem will also "have their death turned to zero", forcing them into a death loop for all eternity. Gold Experience was also pierced by the Arrow during Entering the Gang, Part 4 when Giorno is attacked by Black Sabbath but it is unclear whether this is an oversight on the part of Araki, or Requiem was possible then, but only realized when given a reason to manifest.
Intelligence: Giorno is a very competent tactician. An observer by nature, Giorno likes to assert his opponents' abilities and plans before acting. He then uses his observations to probe for any weakness of their part and predict what they will do, often returning their moves against them. Using his Stand with remarkable imagination, Giorno gives himself a wide range of possibilities, the exploitation of Gold Experience's power and the characteristic of animals he transforms objects into allows Giorno to, among others, reposition himself quickly, or tracking his opponents. Moreover, he is good at using his environment to his advantage. Giorno is quick on his feets, and is able to formulate plans on the spot.
Giorno has shown himself adept at cooperating with other Stand users with maximum effectiveness, particularly Guido Mista with whom he is close. Giorno is able to exploit his partner's power almost as effectively as his own, taking account of their precise abilities and using them in his tactics. Most basic of all is transforming Mista's bullets into other lifeforms to take his enemies by surprise and multiply Giorno's effective range.
Despite seeming to have a reckless side, notably infecting himself with Purple Haze's virus, Giorno is a very careful person, constantly warning his partners of their impatience. He always has backup plans and makes sure his enemies are eliminated. While appearing as heedless, Giorno actually takes calculated risks.
Knowledge: Giorno is very knowledgeable in biology. His encyclopedic knowledge of fauna and flora allows him to transform objects into the lifeforms most suitable to his goal, as well as deducing his enemies' powers.
Charisma: Giorno is a charismatic individual, able to sway people to his side easily, either through speech or key actions. His habits of observing his peers allow him to then deduce the best way to impress them and make them an ally, granting them resolve and confidence when they work with him. Arguably, this trait is likely inherited from his father.
Stealth Thievery: As he himself admitted, Giorno is an accomplished pickpocketer. Although demonstrated only once, his skill is undeniable as he was able to steal a prison guard's wallet in the middle of his body search.
- Giorno has shown the ability to stuff his entire ear into his head, and that was in-fact the very first ability he displayed when he was introduced.
