Glyph of Energy

Acquisition
Signet of Capture:
 * Hyl Thunderwing (Mineral Springs)

Usage
Combine with exhaustion causing or high energy skills. Since it has no linked attribute, this is particularly useful for Mesmers to copy using Arcane Mimicry.

It should also be noted that combined with one of the Attunement skills, this skill reduces the cost of a 25 energy elemental spell to 2.5 energy, with an increase in casting time of one second. 15 Energy elemental spells are reduced to 0.5 energy. Combined with its ability to be reused every 15 seconds, it makes it a very potent Elite.
