Second Wind

Acquisition
Signet of Capture:
 * Snapjaw Windshell (Archipelagos)

Usage Notes

 * This skill is obviously much more powerful when used on primary Elementalists with high Energy Storage, because you can afford a relatively large amount of exhaustion without it being debilitating.
 * The first time this is activated, if the caster doesn't have any exhaustion from other skills, this skill will only provide nine energy, due to recovery from exhaustion during the two second activation time (which only nets +4 total). Repeated castings increase this amount.
 * Increasing exhaustion to more than half of total energy ends is fairly wasteful, as more energy is gained than the maximum energy. In general, it is often best to aim at keeping your exhaustion between 1/3 and 1/2 of your total energy.
 * Second Wind has a two second activation time, longer than similar skills (and notably more interruptable than Energy Boon, Ether Prodigy, Mantra of Recall, or Offering of Blood).
 * Comparing only energy gained to other energy management skills, Second Wind starts outperforming them at about 35 exhaustion (where it provides exactly +1 energy per second when cast every thirty seconds). In order to use Second Wind efficiently, it is best to have at least 70 maximum energy.
 * A major advantage of Second Wind is its flexibility. You can continually adjust how much exhaustion is tolerable against current energy needs.
 * A major disadvantage of Second Wind is how much exhaustion is required to really benefit from it. Recovering from 35 exhaustion takes 115 seconds.  This may require entering future battles with lower than maximum energy, or long waits between battles.

Energy Gain
This presumes Exhaustion is maintained at the level shown (and Second Wind is cast once every thirty seconds).
