List of Final Fantasy X abilities The following is a list of abilities in " Final Fantasy X " , abilities are split into different categories . There are the commands used by the character , and Auto - Abilities which are equipped to the characters through the weapons they have equipped . Abilities . Every character starts off with a number of basic commands . Each character ' s main commands are Attack and Item . Another command appears exclusively to Yuna , the Summon skillset , which allows her to summon aeons she has earned . Going right from the main commands gives the Weapon and Armor commands , which allow the player to change their current equipment , and the Escape command , which allows that player to attempt to remove themselves from battle . Going right from the main commands while controlling an aeon offers a different selection of commands . Shield casts a defensive status on the aeon until their next turn , reducing damage dealt by enemy attacks while preventing the Overdrive gauge from increasing . Similarly , the Boost casts a status which will increase the Overdrive gauge gain from damage taken until their next turn , while increasing the damage inflicted from enemy attacks . Their third skill is Dismiss , which functions like Escape and removes the aeon from battle , and it cannot fail . Aeons all have their own unique abilities . These often are non - elemental ( despite implications from their names ) which have their own special effect , such as inflicting statuses . Exceptions to this are Yojimbo , who has four abilities which cannot be chosen , and the Magus Sisters , who each have their own ability but due to the nature of how they are controlled , are not selected through commands . The player can also put their character in the Defend status for one turn through cancelling a turn by pressing . This command is not present for aeons , who have a Shield command which serves a similar purpose . The Sphere Grid grants access to a further myriad of abilities , found under four skillsets . These are Skill , Special , Wht Magic , and Blk Magic . While aeons do not have their own Sphere Grids , they can still learn a selection of these abilities . Aeons learn abilities through spending items to teach them to the individual aeon . Yojimbo and the Magus Sisters cannot learn these kinds of abilities , however the Magus Sisters may use some Blk Magic and Wht Magic abilities in battle . Overdrives . If the player has a full Overdrive gauge , they gain access to the Overdrive skillset , individual to that character , by going to the left of the main commands . Each character obtains new skills in their Overdrive skillset in different ways . Aeons each have their own Overdrive commands , with exception to Yojimbo and the Magus Sisters who do not respond to simple commands . Yojimbo also has no exclusive Overdrive abilities . Trigger Commands . These are special commands used in specific battles against certain bosses that produces various effects unique to said boss . Sometimes , only certain characters may use Trigger Commands . Auto Abilities . Auto - Abilities are commonly elements or status effects added to attacks , or stat boosts , and less commonly , other special abilities . They occur automatically without the player needing to select a command to automate them , but instead are equipped to a player through weapons and armor . A weapon and armor can have up to four slots , filled with a variety of abilities . Some weapons and armor may come with empty slots . Once the storyline reaches Guadosalam , empty slots can be customized by spending items to add the abilities to the equipment . Auto - abilities cannot be removed from equipment . In addition to changing weapon damage from physical to elemental and the potential to inflict status effects , Magic power and Strength stat increases can also be attached to weapons . Increasing the amount of AP gained from battles , and the rate at which the Overdrive gauge fills are also possible . Other unique abilities found on weapons include Sensor which gives additional information about targets , Capture , an ability used in the Monster Arena sidequest to catch enemies , Overdrive - > AP , which gives the player AP instead of filling their Overdrive gauge , and Break Damage Limit , which exchanges the 9 , 999 Damage cap for a 99 , 999 Damage cap . Auto - Abilities for armor include protection or absorption of elements , or protection or prevention of statuses . Magic defense and Defense stat increases can also be attached to armor . Positive statuses can be permanently induced through various abilities . HP Stroll and MP Stroll , abilities allow their respective stats to be increases as the player travels through the field . Armor with Break HP Limit and Break MP Limit equipped can extend the HP cap from 9 , 999 to 99 , 999 , and MP cap from 999 , to 9 , 999 respectively . There are two abilities that can appear on both weapon and armor . While Magic Counter can be customized to weapons , a Buckler can be bought from Rin on the first visit to Calm Lands . Buckler is the name for a Shield with one slot and no customization , leading players to assume Magic Counter was never supposed to be on armor . Similarly , while No Encounters can be customized to armor , Geosgaeno can drop a weapon with No Encounters equipped ( it may be two or three slots ) when defeated . Similarly , the No Encounters equipped to the weapon will not affect the name and it will have the generic name of a weapon with no abilities equipped . Hidden Bonuses . Some weapons have , theoretically , hidden Auto - Abilities . Weapons dropped by Bomb , Grenade , and Puroboros enemies inflict an eighth more damage than most weapons , having a damage constant of 18 , where normal weapons have 16 . The weapon dropped by Penance will have a Critical Bonus of 10 % , where the normal weapons only have a statistic of 3 % . Some enemies in the Monster Arena and all Dark Aeon s who drop " " - strike " " weapons and " " - proof " " armor also drop weapons with a Critical Bonus statistic of 6 % . The enemies in Monster Arena are : Catoblepas , Don Tonberry , Jormungand and Malboro Menace from Area Conquest ; Fenrir and Sleep Sprout from Species Conquest ; and all Original Creations except Neslug . Celestial Weapon s also have their own bonuses . The Caladbolg , World Champion , Spirit Lance , and Godhand deal more damage the closer their wielder is to maximum HP ; the Nirvana and Onion Knight deal more damage the closer their wielder is to maximum MP ; and the Masamune deals greater damage the lower its wielder ' s HP is .
