Barrage

Acquisition
Signet of Capture:
 * Tyria
 * Markis (Iron Mines of Moladune)
 * Snyk the Hundred Tongue (Abaddon's Mouth)
 * Cantha
 * Aurora (Boreas Seabed)
 * Chkkr Thousand Tail (Drazach Thicket)

Usage Notes

 * Very powerful skill in any scenario where the enemy will be all piled on the tanks.
 * Very useful in PvE for taking out rangers that like to trap (such as Obsidian Behemoths and Armored Cave Spiders), as Barrage can interrupt the traps of multiple foes at once.
 * Positive effects that trigger per attack, such as Zealous/Vampiric bowstrings, Vigorous Spirit and Live Vicariously are quite useful since each use of the skill count as multiple attacks, granting the bonus multiple times.
 * On the other hand, be very careful that you are not hexed with a "damage on attack" hex (eg. Spiteful Spirit, Empathy, Insidious Parasite) when you use this skill, as the recieved damage does stack, and may be quickly fatal. Barraging multiple smiting monks (especially Azure Shadows) that have enchantments that deal damage to the attacker can also kill you quickly.
 * Note that all preparations are removed, so trying to rely on Apply Poison or Ignite Arrow will not work. Instead, use spirits, weapon upgrades, enchantments and weapon spells to boost the basic weapon damage.
