Acquisition
Skill Quests: Skill Trainers:
 * None
 * Captain Greywind (Ascalon Settlement - North Kryta Province)
 * Master Scout Kiera (Henge of Denravi)
 * Dakk (Ember Light Camp)

Usage Notes
Water hexes that slow foes down are very useful in conjunction with Meteor Shower, as they don't get away from the area and get hit and knocked-down. The Ritualist spirit, Earthbind, is very useful with this, as it leaves players knocked-down for 3 seconds, which is enough to be knocked down again (Meteor Shower strikes every 3 seconds).
 * Use Glyph of Energy to nullify exhaustion and reduce this spell's energy cost by 20.
 * Use Glyph of Renewal to eliminate the 60 second cooldown.
 * Use Arcane Echo (if you are a Mesmer) for double casting. Also consider using Glyph of Sacrifice on the echoed Shower. It will not take an extra 30 seconds to recharge since Arcane Echo will change back to its regular state after 20 seconds. Beware of exhaustion though.
