The key that Tserrina drops is still not reliably lootable. I sincerely hope that if this key is required for something on an individual basis that you will either scrub that requirement from whatever it may be for or that you have her start dropping two since most guilds will be out 8 keys before this is fully addressed and fixed.
- - Tserrina Syl`Tor - Tserrina's corpse will no longer move upon success of this raid event. This will hopefully prevent problems with looting the Key of Trauma. This does not appear to be working.
