Respite for a Tormented Soul

Take this Life Crystal, and have your companions take one as well. It contains potent energies from the verdant Dragonshrine in Dragonblight, and it was my own secret to resisting the dark magics of this place for so long. When you face Sindragosa, battle her until she is weakened, and then have your companions use these Crystals to coax out the essence that is dormant within her. If you then defeat her, you should be able to recover it and return it to Wyrmrest Temple in Dragonblight.
