Ping

Definitions

 * A ping is a small colored circle with an expanding "ripple" flash which appears briefly in the Compass to denote a point of interest.
 * Ping is a reference to a player's latency, which is indicated by the Performance Monitor.
 * Pinging a build is sending a build to team chat by ctrl-clicking on the skill bar while in a town or outpost, which can help in coordinating team synergy.

Compass Pings
Pings can be created by players or caused automatically by a quest or mission. They come in several colors:
 * A red ping is caused by a player in your team clicking on the compass or calling a target. Some enemies generate red pings automatically, such as the siege wurms in Dunes of Despair &mdash; which ping at the start of each attack &mdash; or the enemies in the Fissure of Woe.
 * A yellow ping is issued by a mission to indicate important landmarks, areas to avoid, destroy, visit, or otherwise consider. These pings often correlate to instructions from NPCs.
 * A blue ping indicates a mission- or quest-critical bundle item that is laying on the ground. Not all important items will ping the map, vision crystal shards are one example.

Pings are also accompanied by a small chiming "ping" sound.
