Ghast

A Ghast is a neutral Minion in League of Legends described in-game as "A tough monster that takes less damage from physical attacks and steals life each time it strikes. Killing this monster blesses your champion with Move speed and Disable Resistance."

After slaying a Ghast the monster gives you the Crest of Flowing Water Buff that increases your movement speed by 30% and repeals disables.

It is unwise to kill the wraith at a low level, as it has a lot of lifesteal, making it very difficult to kill. Killing the wolves is much easier, plus the attack speed and cooldown reduction buff make it much more useful.

As with most, the buff obtained from killing the wraith is transferred to the killer, and if someone kills them, it is transferred to them.

The buff has a short duration, of only about 1 minute. Use it wisely.



Trivia

 * There is a weaker version of the Ghast on Summoner's Rift, accompanied by 3 weaker red ones who don't have lifesteal.
 * There are two locations that they can spawn on Twisted Treeline: The two camps in the middle of the northern forest. However, either a Wolf or a Ghast can spawn in each camp, and so sometimes you will need to kill a Wolf in order to have a Ghast spawn.
