Invoker

Invoker is a ranged intelligence hero who is very difficult to master. He is unique in that he possesses a total of 14 abilities in his arsenal; three of them - Quas, Wex , and Exort - are reagents and one is his special ultimate Invoke. The three abilities he learns throughout leveling up can have three instances, which serve as the basic ingredients or components for him to create a new ability using his ultimate. Once the reagents or elements are combined, he can invoke one out of ten different abilities. All of his invoked abilities are capable of a multitude of actions, from damaging enemies to aiding his allies, and even saving himself from danger. His three reagents can be upgraded up to level 7 which determines the power and potency of his invoked abilities, making it more powerful than an ordinary spell. Because of this, he can be played in almost any role possible. Invoker can be a carry, semi-carry, ganker, pusher, initiator or even support. His three reagents provide passive attributes with each level, and each instance of his reagents provides a passive bonus, allowing for specialization at early levels and situational boosts at later levels. His extremely flexible nature allows him to use many different combinations of items effectively but also make him dependent on solid builds and a good gold advantage. Because of the extra points needed to level his three reagents, Invoker also has a special Attribute Bonus ability at level 25 that allows him to gain 6 points in all stats.

Trivia

 * In the earliest version of Invoker, the order of instances mattered when Invoke was cast. Invoker therefore had access to 27 spells, including most of the 10 still in the game (though with some differences). For more information, see here.
 * Invoker is (or used to be) a Magus like, who calls him the Rubick rival 01.mp3 Rubick rival 02.mp3  rubick ally 01.mp3 Arsenal Magus.
 * Invoker's Deafening Blast cast response invo ability deafeningblast 06.mp3 "Sonic boom!" is a reference to the signature move of Guile from the Street Fighter fighting game series.
 * Invoker (Along with some players and casters) sometimes jokingly refers to his Chaos Meteor as a meatball ( invo ability chaosmeteor 07.mp3 "Behold the meatball!"), due to their highly similar appearance.
 * One of Invoker's lines when he casts Chaos Meteor is invo ability chaosmeteor 06.mp3 "Gallaron's Abyssal Carnesphere!" Carne is Portuguese, Spanish and Italian for meat, and a sphere is the geometric shape of a ball. So, "carnesphere" is another way of saying "meatball".
 * Invoker's line for purchasing a invo blink 02.mp3 "Dagger of the mind." references the "Dagger" monologue from Shakespeare's play, Macbeth.
 * Invoker's respawn line invo respawn 10.mp3 "Knowing me... knowing you." references the song by the band Abba, of the same name.
 * Invoker's voice actor, Dennis Bateman, also voices the Spy from Team Fortress 2. Invoker's killing response Invo kill 10.mp3 "You die as you lived: insipid and ignorant." is a reference to this, as the Spy also has 2 similar killing responses: "You died as you lived: running away!" and "You died as you lived: morbidly obese!".
 * As referenced in the details of his name, Invoker was known as Kael, or Kael'thas Sunstrider, in DotA. Kael'thas is best known as the Lord of the Blood Elves in the Warcraft universe. The Invoker of DotA also makes use of his Warcraft 3 model and voice.
 * 's responses when meeting Invoker may also be related to this, as Dragonus was also a blood elf in DotA.

Name

 * In DotA, Invoker's name is Kael, based on the WarCraft Blood Elf Mage character, Kael'thas Sunstrider. His fun name is Kal-El, a pun conflating the name Kael with the birth name of Superman.
 * In April 2011, a fake DotA 6.72 Chinese changelog referred to Invoker as "卡尔" ("Kael", transliterated as "Kǎ'ěr"). A PlayDota forum member translated the changelog with Google Translate, in an attempt to get a quick, rough translation. Google Translate mistakenly translated "卡尔" as "Carl". PlayDota forum members were at first confused, then entertained by the mistake. IceFrog, the lead developer of DotA and Dota 2, joked "Carl had it coming".
 * In December 2011, drafts of Invoker's Dota 2 lore referred to him as "Garral" twice, presumably a nod to "Carl". This name was excised upon Invoker's release in January 2012; the lore currently refers to him only as "the Invoker".
 * Invoker's voice lines include the name Carl three times. Invoker has a small chance to speak one of these lines when his model is selected:
 * invo spawn 01.mp3 "Carl!"
 * invo rare 04.mp3 "Throughout the eons I have been known by many names…but my true name of power…is Carl."
 * invo rare 05.mp3 "Behold before you, the illustrious, the imperious, ingenious arch-mage… CARL."
 * Undying uses the name Carl once, when meeting an allied Invoker on the battlefield, and even then only 5% of the time:
 * undying ally 10.mp3 "Carl, is that you?"
 * Mirana uses the name Carl once, when killing an enemy Invoker, and even then only 5% of the time:
 * mir rival 16.mp3 "Carl, meet Sagan." A pun on Carl Sagan. (Mirana's feline mount is named Sagan.)
 * In summary, whether Invoker's "real" name is Carl appears to be a subject of humor and is intentionally ambiguous.
