Kill the Blue Sentinel to receive the 
Crest of Insight, a buff which grants increased mana regeneration (or energy regeneration) as well as cooldown reduction.
Lore
Sentinels, or Stone-golems, are magical fusion of flora, fauna, and rock native to Valoran but can also be found in Ionia and on the Shuriman Continent. Despite its rock like appearance, its behavior is very much of an animal reminiscent of a bear or wolf. The creature is powered by nature magic. 
Smaller forms of this creature are called 
Sentries. 
Ivern has befriended an injured 
stone-golem. Knowing the poor creature was on the verge of death, he fashioned her a new heart from a river pebble. Adhering to the tradition of all mineral beings, the golem became Ivern's devoted life-friend. He named her 
Daisy, after the flowers that mysteriously sprouted from her stone body. Today, if Ivern is threatened, she 
races to his side.
Notes
- Without slows, the Blue Sentinel has a movement speed of 200 [180 (+20)]. When its
patience runs out its movement speed is increased by 20%, to 218 [180 (+36) (+2)].
