Corroded Skeleton Key

The Corroded Skeleton Key costs sixty Frost Emblems. It is a trinket that provides 228 stamina and an activated shield that absorbs 6400 damage and lasts for 10 seconds and has a 2 minute cooldown.

The reason I got this trinket for my warlock is arena and battlegrounds. This trinket is useless for me in instances but a great asset in pvp. I'm really happy with it, it took me a long time to get up enough Frost Emblems since all I do is the daily dungeon and the occasional VOA.

I usually only play my 2v2 arena team with my wife, she is a rogue, and I am a warlock. So nine times out of ten I am targeted first. This shield and stamina give me a lot of protection against getting instant gibbed against double mages and what not.

Plus I am affliction so my character is always gaining health from my corruptions, haunt, and drain life. If I am running low on health I will pop this trinket and absorb some damage while I drain life and get bonus health from the Death's Embrace talent.

Overall I don't know if its really worth the sixty Frost Emblems for every class, but I highly recommend it for warlocks.
