Other Notes

 * This skill can be of great use in places like the Fissure of Woe where the enemies are known to have barrage. This can take some pressure off your healers since it doesn't actually require the party to have a shield to block incoming projectiles. This, combined with ward against melee provide a nice protection against the oncoming enemy without the use of a protection monk.
 * This skill name might be a reference to the Star Trek series. Starfleet captains often give the order "Shields up!" when expecting fire.
 * Basically, this skill becomes very useful against Rangers and monster mobs that consist of Ranger-types. It will save you and your team.
