Skyshards are a collectible item, and are placed throughout the world. Skyshards are optional, and are not required to be collected, except for one in the tutorial quest. For every three Skyshards collected the player receives one skill point.
This is a list of locations by game area, not specific locations, which will be listed on the place pages listed below. Collecting all the Skyshards in one location grants the player an Achievement. In-game, clues to each skyshard's location are listed in the Achievements menu under their respective areas.
