In the original trailer for League of Legends, Sivir's hair was a pink/red color.
Sivir's weapon is inspired by the chakram, which is a throwing disk with razor sharp edges used by Indian Rajput warriors. The weapon is about the size of a frisbee and is thrown in a similar manner. It is capable of causing decapitation, and if deflected by a shield or armor, could bounce off and strike other enemy warriors.
Sivir was the first champion to have a spell rating of 10.
Before her passive was changed, the highest possible dodge chance in the game could be acquired by Sivir with maximum ranked Šablóna:Ai (25% while moving), 9 Tier 3 Seals of Evasion and 3 Quints of Evasion (11.25%), and 6 Ninja Tabi equipped (6 sources, 12% each). This gave her a final dodge modifier of approximately 30.91 (69.09% of attacks are dodged). However, the dodge chance stat has since been removed from the game.
Sivir is one of the few champions to feature two champion spotlights due to significant changes to her kit.
