Invoker

Gameplay
The Invoker is the most well-rounded spellcasting hero, due to his massive array of spells. Using his three elemental reagents and his Invoke ability, the Invoker can utilize a total of 10 different spells. Due to his complexity and fragility, the Invoker is a bad choice for newer players. With some experience, however, he becomes a force to be reckoned with. The Invoker is capable of massive area of effect damage, powerful disabling spells, very strong summons, and potent enchantments. While other spellcasters tend to be focused in one area, the Invoker has the ability to change his role at will. His spells tend to start out weaker than comparable abilities, but since his reagents have 7 levels each his potential spell power is very high.Although mastering his spells takes perhaps the most practice of any hero, he is definitely worth the time.

At level 25, Invoker has 7 points each towards Quas, Wex, and Exort, and 4 points towards Invoke. Uniquely among heroes, Invoker does not possess the Attribute Bonus ability (i.e., he cannot put points towards "Stats"). Instead, he gains a permanent attribute bonus to one of his stats each time he levels up Quas, Wex, or Exort.

Trivia

 * In the earliest version of Invoker, the order of instances mattered when Invoke was cast. Invoker had access to 28 spells, including the 10 still in game.


 * The line "Carl!", that's present in Invoker's responses - designated to be invoked on his spawn, refers to a "leaked" changelog of DotA 6.72, in which "Kael", Invoker's original name, was mistakenly translated as "Carl".
