The Crest of Insight is a buff in League of Legends.
It grants increased mana/energy regeneration, cooldown reduction and ability power (per level).
The buff is available only on Summoner's Rift. It can be identified by swirling blue runes around the champion. Because of this, it is often referred to as the "blue buff" or just "blue".
