The Crest of Insight is a neutral buff granted by the Blue Sentinel Blue Sentinel. It is available only on Summoner's Rift.

The holder of the buff is marked by swirling blue runes around the champion, so the Crest of Insight is often referred to as the blue buff or just blue.

How to obtain

  • By landing the killing blow to the Blue Sentinel Blue Sentinel.
  • By killing a champion that currently possesses this buff, the buff is then passed to the killer. In this case, the duration of the buff is refreshed.
  • After an allied Ivern Ivern (at least level 5) applies and then triggers Friend of the Forest Friend of the Forest on the camp of Blue Sentinel Blue Sentinel; the blue orb within the camp has to be collected.
    • The buff will last for 90 seconds instead of 120 seconds in this case.

Notes

  • The bonus energy restored is 7 per second (5 + 200 × 1%) on most energy-champions, and 9 per second on Shen Shen (5 + 400 × 1%).
  • The buff can only be lost by timing out or death. Receiving the buff while dead will keep it after respawning.

Old Icon

Trivia

  • Its old icon was recycled from Tabu's Tabu's Tattoo Tattoo.
