Snatch, according to King, is an ability that enables its wielders to "rob" physical objects and the abilities of other creatures, without making any actual or direct contact, because it is an intangible attack. "Robbing" objects seems to have the effect of stopping the particular object's motion, and also allows the wielder to grab and pull it; such an ability can be used to stop the usage of equipment during a battle. One drawback is that while the weapons themselves become unusable, techniques that do not require motion are not restricted. This attack is extremely dangerous if used properly, because it bypasses any obstacle on its way, this includes: magic based barriers, armors, battle equipment, etc. 
Wielders are also able to basically steal the physical abilities of their opponents, including speed, stamina and raw strength, and add it to their own, thus strengthening themselves, and weakening their opponents. At his peak of stolen power, Melascula comments his power level roughly surpasses that of Galand at his 26,000 base level, which was heavily weakened. The amount of strength Ban can steal is limited as his body can only contain so much before he reaches his maximum capacity. The advantages this ability gives to his wielder are very good, but there has shown ways to counter it (Which are only two ways) First is by having a power/strength beyond Ban’s own. Second is by manipulating your anatomy (changing or moving parts from your body) in order to confuse Ban since in order for him to steal a body part he needs to know where is located (as shown in the fight against Melascula). This ability becomes less dangerous when the intent is not killing, but stealing, hold or restrain instead (as shown when he tried to grab/restrain Wild. Later in their group conversation Meliodas states that Ban could’ve killed Wild if he wanted to, but that were not his intentions)
After sixty years of failed attempts to steal the Demon King's abilities with Snatch (and getting his own power absorbed instead), Ban starts to feel the sensation of "giving" instead of "taking", and becomes capable of seemingly "give" his own power and strength to others, healing and strengthening them as result. Being immortal, Ban runs no risk of exhausting his life force. However, after transferring the power of the Fountain of Youth to Elaine in order to prevent her from dying, Ban loses his immortality and can no longer infinitely give away his life force.
- Physical Hunt「
身体狩り, Fijikaru Hanto; literally meaning "Body Hunt"」: A characteristic technique of Ban's magic that allows him to temporarily steal all of his opponents physical abilities, including both their strength and speed. These abilities are added to his own.
- Fox Hunt「
獲物狩り, Fokkusu Hanto; literally meaning "Game Hunt"」: A technique best used in conjunction with a far-reaching weapon. Boasting pinpoint accuracy, the technique allows Ban to swiftly grab hold of an object and pull it towards himself, seemingly bypassing any obstructions.
- Banishing Kill「バニシング・キル, Banishingu Kiru」: Ban uses his power to pull himself over a distance, delivering a near instantaneous and fatal slash to his opponent as he is propelled across from them.
- Assault Hunt「
死神の一薙, Asaruto Hanto; literally meaning "Death Single Mowing"」: A powerful but savage attack where Ban is thrust forward, beheading any caught in his path. This technique allows him to dispose of a large group of enemies in a single assault.
- Hunter Fest「
狩りの祭典, Hantā Fesu; literally meaning "Festival of Hunting"」: A technique that allows Ban to steal the physical strength of every living creature within a hundred foot radius of himself. However, as noted by Melascula, there is a limit to how much strength Ban can rob a person from, as seen in his encounter with Galand. Once the limit is reached, Ban is incapable of robbing the person of more power as it puts his own body in danger. After using Hunter Fest to its limit, Ban becomes heavily fatigued to the point that he is incapable of fulfilling the simplest of tasks such as walking.
- Zero Sign「
絶気配, Zero Sain; literally meaning "Suppressed Presence"」: A technique that somehow makes Ban invisible and undetectable, possibly by "stealing" one's perception of him and making it easy to sneak up on enemies. Effective enough that Monspeet who was able to sense people watching him through a crystal ball hundreds of meters away was still unable to sense Ban when using this ability. 
- Crazy Hunt「
乱獲, Kureijī Hanto; literally meaning "Over-hunting"」: A technique used by Ban to extract the vital organs of multiple enemies simultaneously. 
贈与, Gifuto」: Using this technique, Ban is able to transfer his own life force and strength to another being. Having lost his immortality, the limit in how much of his strength he can give is yet uncertain. 
- Crazy Rush「クレイジー・ラッシュ, Kureijī Rasshu」: A technique that attacks multiple enemies in a single moment no matter the distance. 
- The aspect of "robbing" physical objects and abilities conforms with Ban's title as the Sin of Greed, greed being an inordinate desire to possess wealth, goods, or objects of abstract value.
