From Guild Wars 2 Wiki
Updrafts allow players to ascend while they are gliding. In order to be able to use updrafts, players must have the Updraft Use mastery unlocked.
- Heart of Maguuma
- Entering an updraft with a glider deployed will also refill the glider's stamina bar.
- While updrafts are not currently marked on the maps in the Heart of Maguuma, there are four updraft icons in the raid map by Gorseval's Perch in Spirit Vale indicated via the icon .
