Celestial skill

Celestial skills are special very powerful skills granted to players by the dragon Kuunavang. Much like Resurrection Signets, a celestial skill becomes disabled after it has been used once until recharged by a Morale Boost.

Celestial skills appear in the following areas:
 * Raisu Palace mission
 * Raisu Palace (Explorable)
 * Imperial Sanctum mission.

Usage Notes

 * Celestial skills are skills, and thus it is possible to Echo chain them. Which means that a powerful skill like Celestial Storm can be invoked 3 times in a row. This is a principal difference from Resurrection Signet, which cannot be echoed.
 * It is possible to replace a maintained enchantment such as Divine Boon with a celestial skill after the enchantment has been cast without losing the enchantment. Note that Shiro himself has no disenchanting ability, but he may use Echoing Banishment to summon a Bound Mesmer or Bound Necromancer. These mobs have disenchanting skills, so replacing important maintained enchantments can be risky.
 * Consider replacing Charm Animal with your celestial skill, the pet won't vanish!
