I am willing to trade all of the following things for a Lv. 70 Shield of Ages:
Reactive Viral Marketer
Celestial Enforcer COM
Oxidizer Oz Kit
Ack Ack Oz Kit
Fabled Tortoise Shield
All of these are Lv. 70. I had a big Golden Chest / Grinder blowout. Spent almost my entire stash of keys.
My GT is Iaeyan Elyuex. My Enforcer has a lot of shield-boosting abilities, so this shield will work well for him.
