Usage
This skill provides a viable alternative to Adrenaline based skills, as you will receive three energy per hit (or four with a Zealous weapon upgrade), which can be used both to gain large quantities of energy to fuel skills of your secondary profession, or to reduce the cost of most warrior attack skills to a mere two energy each, as nearly all energy-based Warrior skills cost five energy. In addition, the means in which this skill works often make it preferable to Flourish, as Warrior's Endurance provides a continuous flow of energy rather than a single spike, which most warriors will not be able to take advantage of. Furthermore, Warrior's Endurance is used beforehand rather than afterwards, as Flourish is. This is an advantage because you will naturally have the energy available before you spend any, whereas to use Flourish you need at least five energy left over after using your expensive skills but before receiving the extra energy from Flourish. The downside is that Flourish recharges skills and can potentially give back more energy, whereas Warrior's Endurance does not.

Due to its long duration, Warrior's Endurance can also be used to keep item attributes with the "while in a stance" prerequisite active for a very long time, without the detrimental effects of most other stances.
